How Do You Use CAS On A Graphing Calculator?
Some graphing calculator models include an integrated computer algebra system (CAS) for performing symbolic calculations. A symbolic approach to problem solving can be much more informative than a numerical approach. The following steps apply specifically to HP graphing calculator models with CAS, but the same general approach applies almost universally. Hit the “CAS” button in the home view of the graphing calculator to enter the CAS environment. The menus for CAS appear on the bottom of the screen and offer a range of functions and adjustable parameters. Configure the CAS settings. Depending on the type of problem you’re solving, you may need to set the parameters carefully. Alternatively, if you want just the basic default settings, configure the settings to default using the “ALGB” menu and the “CFG” option. Enter the equation or expression that you want to manipulate or solve. If you’re working with a single variable, you can just use the “X, T, Theta” button to quickly enter the
