The first time you open the Scratchpad, a blank page opens with the Calculator active. ▶ Press » to alternate between the Calculate and Graph pages. ▶ Press b to see the Scratchpad Calculate or Scratchpad Graph menu.
Calculating with Scratchpad From the Scratchpad Calculate page, enter a math expression on the entry line, and then press · to evaluate the expression. Expressions are displayed in standard mathematical notation as you enter them. Each evaluated expression and result becomes part of the Scratchpad history, displayed above the entry line. Entering Simple Math Expressions Note: To enter a negative number, press v and then type the number. Suppose you want to evaluate 1.
Note: Results formatting can also be adjusted in settings. For more information about customizing settings, see Configuring Handhelds. Inserting Items from the Catalog You can use the Catalog to insert functions and commands, symbols, and expression templates into the entry line. 1. Press k to open the Catalog. By default, the first tab is displayed, which lists all commands and functions in alphabetical order. 2.
3. Use the arrow keys to move the cursor to each element’s position, and type a value or expression for each element. 4. Press · to evaluate the expression. Inserting Expressions Using a Wizard You can use a wizard to simplify entering some expressions. The wizard contains labeled boxes to help you enter the arguments in the expression. For example, suppose you want to fit a y=mx+b linear regression model to the following two lists: {1,2,3,4,5} {5,8,11,14,17} 1.
LinRegMx function in a non-CAS or Exact Arithmetic handheld LinRegMx function in a CAS handheld 7. Press ·. A wizard opens, giving you a labeled box to type each argument. 8.

• • The string undef is displayed instead of a value when you move over a point that is not defined for the function (a discontinuity). When you trace beyond the initially visible graph, the screen pans to show the area being traced. 4. Press d or choose another tool to exit Graph Trace. Finding Points of Interest You can use the tools on the Analyze Graph menu to find a point of interest in a specified range of any graphed function.
4. Press · at the point to start the search. The tool shades the range. If the search region you specified includes the point of interest, a label for the point is displayed. If you change a graph that has points of interest identified, be sure to check for changes in points of interest. For example, if you edit the function on the entry line or manipulate a plot, the point where the graph intersects zero can change. The labeled points of interest remain visible on the graph.
4. If a document is open, select either New or Current document. 5. Click Save. • • If you selected to save to a current (open) document, the Scratchpad pages are added to the document.
