What's New What's New in the TI-84 Plus CE Reference Guide: All items listed are new or updated entries in the Reference Guide for the TI-84 Plus CE Graphing Calculator. Piecewise • New piecewise function to support entry of functions as they are seen in textbook. This command can be found in » MATH B:piecewise( . • New CONDITIONS submenu in y : supports faster entry of intervals for piecewise functions. • Available for use in all function graphing modes and all split screen modes.
Introduction In this Reference Guide you will find the following information: • CATALOG, Strings, Hyperbolic Functions - Includes instructions on browsing, using, entering strings, and other functions in the CATALOG.
CATALOG, Strings, Hyperbolic Functions What Is the CATALOG? The CATALOG is an alphabetical list of all functions and instructions on the TI-84 Plus CE.
Browsing the TI-84 Plus CE Catalog Selecting an Item from the CATALOG To browse and select a CATALOG item, follow these steps. 1. Press y Nto display the CATALOG. The 4 in the first column is the selection cursor. 2. Press † or } to scroll the CATALOG until the selection cursor points to the item you want. • • • To jump to the first item beginning with a particular letter, press that letter; alpha-lock is on.
MathPrint™ Classic CATALOG, Strings, Hyperbolic Functions 5
Using Catalog Help Displaying Catalog Help You can display Catalog Help arguments for functions in two ways: • Using an alpha/numeric function listing in the catalog (e.g, y N). • Using the functions listed in certain menus (e.g, »). Catalog Help lists the valid arguments for the function under the edit line. Arguments in brackets are optional. 1. Display the menu that contains the function. 2. Use } and/or † to move the cursor to the function. 3. Press à to display arguments for the function.
• Use shortcut menus ƒ ^ through a through for argument values if available. • Enter your argument values on the function edit line, and then select PASTE to paste the function and the argument values you entered. Note: You can paste to most cursor locations. • Select ESC to exit the Catalog Help screen.
Entering and Using Strings What Is a String? A string is a sequence of characters that you enclose within quotation marks. On the TI-84 Plus CE, a string has two primary applications. • It defines text to be displayed in a program. • It accepts input from the keyboard in a program. Characters are the units that you combine to form a string. • Each number, letter, and space counts as one character.
Storing Strings to String Variables String Variables The TI-84 Plus CE, has 10 variables to which you can store strings. You can use string variables with string functions and instructions. To display the VARS STRING menu, follow these steps. 1. Press ½ to display the VARS menu. Move the cursor to 7:String. 2. Press Í to display the STRING secondary menu. Storing a String to a String Variable To store a string to a string variable, follow these steps. 1. Press ƒ W, enter the string, and press ƒ W. 2.
The string variable is pasted to the current cursor location, next to the store symbol (!). 5. Press Í to store the string to the string variable. On the home screen, the stored string is displayed on the next line without quotation marks. Displaying the Contents of a String Variable To display the contents of a string variable on the home screen, select the string variable from the VARS STRING menu, and then press Í. The string is displayed.
String Functions and Instructions in the CATALOG Displaying String Functions and Instructions in the CATALOG String functions and instructions are available only from the CATALOG.

The ellipses in the table indicate the presence of additional CATALOG items. CATALOG ... Equ4String( ... expr( ... inString( ... length( ... String4Equ( sub( ... Converts an equation to a string.
Selecting a String Function from the CATALOG To select a string function or instruction and paste it to the current screen, follow the steps for selecting an item from the CATALOG. Equ4String( Equ4 String( converts an equation to a string. The equation must be store in a VARS Y-VARS variable. Yn contains the equation. Strn (from Str1 to Str9, or Str0) is the string variable to which you want the equation to be stored.
Note: If string does not contain substring, or start is greater than the length of string, inString( returns 0. length( length( returns the number of characters in string. string can be a string or string variable. Note: An instruction or function name, such as sin( or cos( , counts as one character. length( string) String4Equ( String4 Equ( converts string into an equation and stores the equation to Yn. string can be a string or string variable. String4 Equ( is the inverse of Equ4 String( .
sub( sub( returns a string that is a subset of an existing string. string can be a string or a string variable. begin is the position number of the first character of the subset. length is the number of characters in the subset. sub( string,begin,length) Entering a Function to Graph during Program Execution In a program, you can enter a function to graph during program execution using these commands.
Note: When you execute this program, enter a function to store to Y3 at the ENTRY= prompt.

Error Messages When the TI-84 Plus CE detects an error, it returns an error message as a menu title, such as ERR:SYNTAX or ERR:DOMAIN . This table contains each error type, possible causes, and suggestions for correction. The error types listed in this table are each preceded by ERR: on your graphing calculator display. For example, you will see ERR:ARCHIVED as a menu title when your graphing calculator detects an ARCHIVED error type.
ERROR TYPE Possible Causes and Suggested Remedies required. In an editor, you entered a type that is not allowed, such as a matrix entered as an element in the stat list editor. You attempted to store an incorrect data type, such as a matrix, to a list. You attempted to enter complex numbers into the n/d MathPrint™ template.
ERROR TYPE NEST Possible Causes and Suggested Remedies a function, such as seq( within expression for seq( . INCREMENT The increment, step, in seq( is 0 or has the wrong sign. . The TI-84 Plus CE allows for undefined values on a graph. The increment in a For( loop is 0. INVALID You attempted to reference a variable or use a function where it is not valid. For example, Yn cannot reference Y, Xmin, @X, or TblStart.
ERROR TYPE MEMORY Possible Causes and Suggested Remedies Memory is insufficient to perform the instruction or function. You must delete items from memory before executing the instruction or function. Recursive problems return this error; for example, graphing the equation Y1=Y1. Branching out of an If / Then, For( , While, or Repeat loop with a Goto also can return this error because the End statement that terminates the loop is never reached. Attempting to create a matrix with larger than 400 cells.
ERROR TYPE SINGULARITY Possible Causes and Suggested Remedies expression in the solve( function or the equation solver contains a singularity (a point at which the function is not defined). Examine a graph of the function. If the equation has a solution, change the bounds or the initial guess or both. STAT You attempted a stat calculation with lists that are not appropriate. Statistical analyses must have at least two data points. Med-Med must have at least three points in each partition.
ERROR TYPE Possible Causes and Suggested Remedies OS. TI-84 Plus CE and TI-84 Plus share programs but a version error will be given if any new TI-84 Plus CE programs may need to be adjusted for the high resolution graph area. WINDOW RANGE A problem exists with the window variables. You defined Xmax Xmin or Ymax Ymin. You defined qmax qmin and qstep > 0 (or vice versa). You attempted to define Tstep=0. You defined Tmax Tmin and Tstep > 0 (or vice versa).
