You can usually press c or d to get out of a place you don’t want to be. If you make a mistake, you can press . or / Z to “undo.” This works like the backspace key and “undo” menu choice on a computer. Try it: key in a problem on the scratchpad calculator, then make a change to your problem before pressing · . You will probably use the Scratchpad frequently for calculations and graphing functions, but you can also create, use and save multi-page documents with calculations, graphs, geometric figures, lists and spreadsheets, text (“Notes”) and data the you collect with scientific instruments. If you are in Scratchpad, you can press d , or c and 4: CURRENT to get back to your “current” document.

Graphing Functions 11. Press / ~ “Add Graphs” to add a function graphing page to your document. At the top of the screen you will see the function entry line, f1(x)=. (example: f1(x)=3x+4) a. Key in a function of your choice and press · to see your graph and function. Use the letter x for your variable. b. Press e to re-open the function line. It will now be on f2(x)= . Key in another function that will intersect your first function with the intersection point visible on the screen. (example: f2(x)= -2x+1) c. Using the b key, see if you can find at least two ways to locate the point of intersection.

You can also do calculations within a math box. 14. How could you use Notes pages in math class? ________________________________________

Lists & Spreadsheets, Data & Statistics 15. Press / ~ and “Add Lists & Spreadsheets.” Collect some data from several people sitting near you and key it in as shown. Put the Label in the top row (marked with a label), skip the row with the = sign, and put your data into the numbered rows. Be sure to press · when you are done. 16. Press / ~ and “Add Data & Statistics.” Move the cursor to “Click to add variable” and experiment with the graphs you can create. Use the b key for more options.

Geometry 17. Press / ~ and “Add Geometry.” Use the b key to find the Geometry tools. Experiment with drawing shapes and lines. With the 2: View menu, you can graph in 3D!
