Lists & Spreadsheet inserts the leading equal sign (=) for the formula. If the column is a named list, Lists & Spreadsheet inserts listname:= followed by the cursor. 2. Type the expression for the formula after the = and press Enter Use brackets ([]) after any column letter you include in the formula. For example, type =a[]^2 to create a column of values in which each cell is the square of the corresponding cell of column A.
4. Generate (Recalculate) a new set of random numbers: Windows®: Press Ctrl +R. Mac®: Press “+R. Handheld: Press / R. Generating a Numerical Sequence 1. Click any cell in the column in which you want to generate the sequence. 2. From the Data menu, select Generate Sequence . The Sequence dialog box opens. 3. Type the Formula that will be applied to the column values. 4. Type any Initial Terms required by the sequence. Separate them with commas. 5.
8. (Optional) Type a maximum value for the sequence in the Ceiling Value field. 9. Click OK . Lists & Spreadsheet shows the formula in the formula cell and fills the column with the results. Graphing Spreadsheet Data You can graph the data in a spreadsheet using Quick Graph or Summary Plot. Lists & Spreadsheet cells that contain no data are not represented by data points on graphs.
2. Select both columns. 3. From the Data menu, select Quick Graph . A Data & Statistics application is added to the page with the plotted data. The leftmost of the two lists is plotted on the x axis, and the other list is plotted on the y axis. 4. (Optional) Use the Data & Statistics features to analyze or visually enhance the graph. Note: For more information, see Using Data and Statistics.
Creating a Summary Plot from a Summary Table In this example, you create a summary table from raw data, and then use the table to generate a summary plot. For more information, see Using Data & Statistics. raw data summary table for eye color based on raw data A summary table contains an X (or Y) List and a Summary List. • The X (or Y) List contains numeric or string values (such as 1999 or “color”). Numeric values result in a histogram. String values identify the categories for a bar chart.
1. Create a list that holds the category identifiers. For this example, name the list “color” and type strings for eye color. Enclose category names in quotes to prevent them from being interpreted as variables. 2. Create the summary list. For this example, name the list “counts” and type the total count for each of the eye colors. 3. Select either list by clicking the top cell of the column and pressing ▲. 4. From the Data menu, select Summary Plot. The Summary Plot dialog box opens. 5.
Note: In this example, the X List contains string data, so the summary plot displays as a bar chart. The category strings from the list display beneath the bars. Exchanging Data with Other Computer Software You can use the TI-Nspire™ desktop software to copy table data to and from software outside the TI-Nspire™ applications, such as TI DataEditor (in the TI Connect™ software) and Excel® spreadsheet software.
5. Click Edit > Copy. 6. In Lists & Spreadsheet, click the cell where you want the data to be pasted.

Paste the data. Windows®: Press Ctrl +V . Mac®: Press “+V . Handheld: Press / V. Note: Categorical data must be enclosed in quotes (“ “) after the data is pasted.
4. Replace the letters “var” with the name of the variable to capture from Graphs & Geometry. For example, type area. The formula cell now contains an expression similar to =capture (area,0). Note: The argument “0” tells Lists & Spreadsheet that you want to trigger each capture manually. 5. Press Enter. 6. From the Graphs & Geometry application, change the object with a measured value stored as the variable (area, in this example) referenced in the data capture expression. 7.
This lets you set up multiple columns of synchronized captures, such as the x and y coordinates of a moving object. 1. Clear all columns that you will be using for the captured data. 2. Make sure any data values that you want to capture are linked to variable names. 3. Click the column formula cell (the second cell from the top) of the column in which you want to capture the values. 4. Click Data >Data Capture >Automatic.
7. Press Enter to complete the formula. 8. If you are capturing multiple columns of synchronized data, set up the additional columns. For example, you might set up a second capture variable using =capture(objpathY,1,objpathX). 9. When you are ready to capture the values, begin moving the object or start the animation that affects it in Graphs & Geometry. Each captured value is added to the end of the list.

Note: The results are linked to the source data. For example, you can change a value in Column A, and the equation updates automatically. Supported Distribution Functions The following distributions are available from the Lists & Spreadsheet application. For more information regarding these functions, see the TI-Nspire™ Reference Guide. • To return a single distribution result based on a single value, type the function in a single cell.
This distribution is used to determine the probability of the occurrence of a certain value in a normal distribution. The draw option is available when Normal PDF is invoked from a formula cell. When you access distributions from the formula cell, you must select a valid list from the drop-down list to avoid unexpected results. If accessed from a cell, you must specify a number for the x-value. The distribution returns the probability that the value you specify will occur.
t Cdf (tCdf) Computes the Student-t distribution probability between Lower Bound and Upper Bound for the specified df (degrees of freedom). You can click the Draw (Shade area) check box to shade the area between the bounds. Changes to the initial Lower Bound and Upper Bound automatically update the distribution.
F Pdf (F Pdf()) Computes the probability density function (pdf) for the F distribution at a specified x value. numerator df (degrees of freedom) and denominator df must be integers > 0. The probability density function (pdf) is: where n = numerator degrees of freedom d = denominator degrees of freedom This distribution is useful in determining the probability that two samples have the same variance. The draw option is available when F Pdf is invoked from a formula cell.
This distribution is useful in determining the probability of a success on one trial before all trials are completed. For example, if heads is a successful coin toss and you plan to toss the coin 10 times, this distribution would predict the chance of obtaining heads at least once in the 10 tosses. Poisson Pdf (poissPdf()) Computes a probability at x for the discrete Poisson distribution with the specified mean, μ, which must be a real number > 0. x can be an integer or a list of integers.
This distribution is useful in determining the probability associated with the first success occurring during trials 1 through n . For example, you could use this calculation to determine the probability that heads display on toss #1, #2, #3, ..., #n . Confidence Intervals Supported Confidence Intervals The following confidence intervals are available from the Lists & Spreadsheets application. For more information regarding these functions, see the TI-Nspire™ Reference Guide.
2-Sample t Interval (tInterval_2Samp) Computes a confidence interval for the difference between two population means (m1Nm2) when both population standard deviations (s 1 and s 2) are unknown. The computed confidence interval depends on the user-specified confidence level. This test is useful in determining if there is statistical significance between the means of two samples from the same population.
Stat Tests Supported Statistical Tests Hypothesis tests are available from the Lists & Spreadsheets application. For more information regarding these functions, see the TI-Nspire™ Reference Guide. Some of the wizards for Stat Tests display a Draw check box. By default, the box is not selected. Selecting the box creates a Data & Statistics work area on the page and plots the results in that work area.
This test is useful in determining if two normally distributed populations have equal means, or when you need to determine if a sample mean differs from a population mean significantly and the population standard deviation is unknown. 2-Sample z Test (zTest_2Samp) Tests the equality of the means of two populations (m1 and m2) based on independent samples when both population standard deviations (s 1 and s 2) are known. The null hypothesis H0: m1=m2 is tested against one of the alternatives below.
2-Prop z Test (zTest_2Prop) Computes a test to compare the proportion of successes (p1 and p2) from two populations. It takes as input the count of successes in each sample (x and 1 x ) and the count of observations in each sample (n and n ). 2-Prop z Test 2 1 2 tests the null hypothesis H0: p1=p2 (using the pooled sample proportion Ç) against one of the alternatives below.
df(x, n1N1, = Fpdf( ) with degrees of freedom df, n1N1, and n2N1 n2N1) = reported p value p 2-Sample FTest for the alternative hypothesis s 1 > s 2. 2-Sample FTest for the alternative hypothesis s 1 < s 2. 2-Sample FTest for the alternative hypothesis s 1ƒs 2. Limits must satisfy the following: where: [Lbnd,Ubnd]=lower and upper limits The F-statistic is used as the bound producing the smallest integral. The remaining bound is selected to achieve the preceding integral’s equality relationship.
ANOVA (ANOVA) Computes a one-way analysis of variance for comparing the means of 2 to 20 populations. The ANOVA procedure for comparing these means involves analysis of the variation in the sample data. The null hypothesis H0: m1=m2=...=mk is tested against the alternative Ha: not all m1...mk are equal. The ANOVA test is a method of determining if there is a significant difference between the groups as compared to the difference occurring within each group.
To select an alternative hypothesis, move the cursor to the appropriate alternative, and then press Enter. Selecting the Pooled Option Pooled (2-Sample t Test and 2-Sample t Interval only) specifies whether the variances are to be pooled for the calculation. • Select No if you do not want the variances pooled. Population variances can be unequal. • Select Yes if you want the variances pooled. Population variances are assumed to be equal. To select the Pooled option, select Yes from the drop-down list.

Libraries A library is a TI-Nspire™ document that contains a collection of variables, functions, and/or programs that have been defined as library objects. Unlike ordinary variables, functions, and programs, which can be used only within a single problem (the problem in which they are defined), library objects are accessible from any document. You can even create public library objects that appear in the TI-Nspire™ Catalog.
Creating Libraries and Library Objects A document is regarded as a library when it is saved or copied to the designated library folder. The default location is: • Windows®: My Documents\TI-Nspire\MyLib. • Mac®: Documents/TI-Nspire/MyLib. • Handheld: MyLib If the folder has been inadvertently deleted, you must create it before attempting to use libraries. You can define library objects using either the Program Editor or the Calculator application.
basic, low-level tasks. Typically, private library objects are called upon by the public functions and programs. A Public library object appears in the Catalog’s library tab after you refresh the libraries. You can access a public library object through the Catalog or by typing its name. Mac® only: In version 1.4 of the software, a library document name cannot contain extended characters, such as Ö, á, or ñ.
• If you defined the object using the Program Editor, it has been stored using Check Syntax & Store from the Program Editor menu. • The libraries have been refreshed. Refreshing the Libraries ▶ Refresh libraries to make the library objects available to your documents. - From the Tools menu, click Refresh Libraries. Handheld: Press / b and click Refresh Libraries. Using a Public Library Object 1. Refresh the libraries. 2.
For example, suppose the library document linalg contains functions named clearmat, cofactor, gausstep, help, inversestep, kernelbasis, rank, and simultstep. Executing libShortcut(“linalg”,“la”) would create a variable group containing the following members: la.clearmat la.cofactor la.gausstep la.help la.inversestep la.kernelbasis la.rank la.simultstep You can refer to those library objects from within the current problem by typing their variable names or by selecting them from the Variables menu.

Getting Started with the Program Editor You can create user-defined functions or programs by typing definition statements on the Calculator entry line or by using the Program Editor. The Program Editor offers some advantages, and it is covered in this section. For more information, see Calculator. • The editor has programming templates and dialog boxes to help you define functions and programs using correct syntax.
 Status line shows line-number information and the name of the function or program being edited. An asterisk (*) indicates that this function is “dirty,” which means that it has changed since the last time its syntax has been checked and it has been stored. Defining a Program or Function Starting a new Program Editor 1. Make sure you are in the document and problem in which you want to create the program or function. 2. Click Insert button on the application toolbar, and select Program Editor > New.
Entering Lines into a Function or Program The Program Editor does not execute the commands or evaluate expressions as you type them. They are executed only when you evaluate the function or run the program. 1. If your function or program will require the user to supply arguments, type parameter names in the parentheses that follow the name. Separate parameters with a comma. 2. Between the Func and EndFunc (or Prgm and EndPrgm) lines, type the lines of statements that make up your function or program.
Inserting Comments A comment symbol (©) lets you enter a remark. Comments can be useful to someone viewing or editing the program. Comments are not displayed when the program runs, and they have no effect on program flow. Define LibPub volcyl(ht,r) = Prgm ©volcyl(ht,r) => volume of cylinder À Disp “Volume =”, approx(p ¦ r2 ¦ ht) ©This is another comment. EndPrgm À Comment showing required syntax.
Storing the Function or Program You must store your function or program to make it accessible. The Program Editor automatically checks the syntax before storing. An asterisk (*) is displayed in the upper left corner of the Program Editor to indicate that the function or program has not been stored. ▶ From the Check Syntax & Store menu, click Check Syntax & Store . If the syntax checker finds any syntax errors, it displays an error message and tries to position the cursor near the first error.
4. Use the arrow keys to view the function or program. 5. If you want to edit the program, click Edit. Handheld: Press e to highlight Edit, and then press ·. Note: The Edit selection is available only for functions and programs defined in the current problem. To edit a library object, you must first open its library document. Opening a Function or Program for Editing You can open a function or program from the current problem only. Note: You cannot modify a locked program or function.
2. Select the Library Name . 3. Select the Name of the object. 4. If you want the imported object to have a different name, type the name under Import As. Creating a Copy of a Function or Program When creating a new function or program, you might find it easier to start with a copy of the current one. The copy that you create is not locked, even if the original is locked. 1. From the Actions menu, click Create Copy. 2. Type a new name, or click OK to accept the proposed name. 3.
2. Type a new name, or click OK to accept the proposed name. 3. If you want to change the access level, select Library Access, and select a new level. Changing the Library Access Level 1. From the Actions menu, click Change Library Access. 2. Select the Library Access: - To use the function or program only from the current Calculator problem, select None . - To make function or program accessible from any document but not visible in the Catalog, select LibPriv.
2. Type the text that you want to find. 3. Type the replacement text. 4. Click Replace to replace the first occurrence after the cursor position. —or— Click Replace All to replace every occurrence. Note: If the text is found in a math template, a message is displayed to warn you that your replacement text will replace the whole template—not just the found text. Closing the Current Function or Program ▶ From the Actions menu, click Close .
- Mac®: Hold down the F5 key and press Enter repeatedly. - Handheld: Hold down the c key and press · repeatedly. Using Short and Long Names Anytime you are in the same problem where an object is defined, you can access it by entering its short name (the name given in the object’s Define command). This is the case for all defined objects, including private, public, and non-library objects. You can access a library object from any document by typing the object’s long name.
5. Press ·. Using a Private Library Function or Program To use a Private library object, you must know its long name. For example, the long name of the object defined as func1 in the library document lib1 is lib1\func1 . Note: If you cannot remember the exact name or the order of arguments required for a private library object, you can open the library document or use the Program Editor to view the object. 1.
If the function or program requires you to supply one or more arguments, type the values or variable names inside the parentheses. prog1(34,power) 3. Press ·. Interrupting a Running Program While a function or program is running, the busy pointer } is displayed. ▶ To stop the function or program, - Windows®: Hold down the F12 key and press Enter repeatedly. - Mac®: Hold down the F5 key and press Enter repeatedly. - Handheld: Hold down the c key and press · repeatedly. A message is displayed.
Letting the User Assign the Values to Variables A program or function can refer to variables created beforehand. This method requires users to remember the variable names and to assign values to them before using the object. 1. Define the program. Define calculatearea()= Prgm area:=w*h EndPrgm 2. Supply the variables, and then run the program. w:=3 : h:=23.64 calculatearea() :area 70.
Requesting the Values from the User (Programs Only) You can use the Request and RequestStr commands in a program to make the program pause and display a dialog box prompting the user for information. This method does not require users to remember variable names or the order in which they are needed. You cannot use the Request or RequestStr command in a function. 1. Define the program. Define calculatearea()= Prgm Request "Width: ",w Request "Height: ",h area:=w*h EndPrgm 2.
cos(π/4) © Displaying Information in the History You can use the Disp command in a program or function to display information, including intermediate results, in the history. © Disp 12•6 Disp "Result:",cos(π/4) © Displaying Information in a Dialog Box You can use the Text command to pause a running program and display information in a dialog box. The user clicks OK to continue or clicks Cancel to stop the program. You cannot use the Text command in a function.
Local i À For i,0,5,1 Disp i EndFor Disp i À Declares variable i as local. Note: When possible, declare as local any variable that is used only within the program and does not need to be available after the program stops. What Causes an Undefined Variable Error Message? An Undefined variable error message is displayed when you evaluate a userdefined function or run a user-defined program that references a local variable that is not initialized (assigned a value).
Note (CAS): Functions and programs cannot use a local variable to perform symbolic calculations. CAS: Performing Symbolic Calculations If you want a function or program to perform symbolic calculations, you must use a global variable instead of a local. However, you must be certain that the global variable does not already exist outside of the program. The following methods can help.
Calling One Program from Another One program can call another program as a subroutine. The subroutine can be external (a separate program) or internal (included in the main program). Subroutines are useful when a program needs to repeat the same group of commands at several different places. Calling a Separate Program To call a separate program, use the same syntax that you use to run the program from the entry line.
À Declares the subroutine as a local variable. Á Defines the subroutine. Â Calls the subroutine. Note: Use the Program Editor’s Var menu to enter the Define and Prgm...EndPrgm commands. Notes about Using Subroutines At the end of a subroutine, execution returns to the calling program. To exit a subroutine at any other time, use Return with no argument. A subroutine cannot access local variables declared in the calling program.
• Control structures such as If...EndIf commands use a conditional test to decide which part of a program to execute. • Loop commands such as For...EndFor repeat a group of commands. Using If, Lbl, and Goto to Control Program Flow The If command and several If...EndIf structures let you execute a statement or block of statements conditionally, that is, based on the result of a test (such as x>5). Lbl (label) and Goto commands let you branch, or jump, from one place to another in a function or program.
Á Displays the value of: 2x if x>5 x if x{5 Note: EndIf marks the end of the Then block that is executed if the condition is true. If...Then...Else...EndIf Structures To execute one group of commands if a conditional test is true and a different group if the condition is false, use this structure: If x>5 Then Disp "x is greater than 5" À 2¦x&x À Else Disp "x is less than or equal to 5" Á 5¦x&x Á EndIf Disp x  À Executed only if x>5. Á Executed only if x{5.
Lbl labelName name to assign to this location (use the same naming convention as a variable name) You can then use the Goto command at any point in the function or program to branch to the location that corresponds to the specified label. Goto labelName specifies which Lbl command to branch to Because a Goto command is unconditional (it always branches to the specified label), it is often used with an If command so that you can specify a conditional test.
For variable, begin , end , increment À Á Â Ã À Name of a variable to be used as a counter Á Value assigned to variable when the For loop begins. Â Value compared to the current value of variable at each iteration of the loop. The loop exits when variable exceeds end . Ã Value added to variable at each iteration of the loop (This argument is optional. The default increment is 1.) At each iteration of the For loop, the variable value is compared to the end value.
You can set end to a value less than begin , provided you also set increment to a negative value. • While...EndWhile Loops A While...EndWhile loop repeats a block of commands as long as a specified condition is true. The syntax of the While command is: While condition When While is executed, condition is evaluated. If condition is true, the loop is executed; otherwise, control jumps to the command following EndWhile . Note: The While command does not automatically change the condition.
 Increments x. à Displays 5. When x increments to 5, the loop is not executed. Loop...EndLoop Loops A Loop...EndLoop creates an infinite loop, which is repeated endlessly. The Loop command does not have any arguments. Typically, you insert commands in the loop that let the program exit from the loop. Commonly used commands are: If, Exit, Goto , and Lbl (label). For example: 0&x Loop Disp x x+1&x If x>5 À Exit EndLoop Disp x Á À An If command checks the condition.
The If command could also use a Goto command to transfer program control to a specified Lbl (label) command. Repeating a Loop Immediately The Cycle command immediately transfers program control to the next iteration of a loop (before the current iteration is complete). This command works with For...EndFor, While...EndWhile , and Loop...EndLoop . Lbl and Goto Loops Although the Lbl (label) and Goto commands are not strictly loop commands, they can be used to create an infinite loop.
Debugging Programs and Handling Errors After you write a function or program, you can use several techniques to find and correct errors. You can also build an error-handling command into the function or program itself. If your function or program allows the user to select from several options, be sure to run it and test each option. Techniques for Debugging Run-time error messages can locate syntax errors but not errors in program logic. The following techniques may be useful.
Using the TI-SmartView™ Emulator With three layout options to choose from, teachers will find that the emulator facilitates classroom presentations.
