The days of a consistent user interface with Scientific Graphing Calculators from Texas Instruments seem to be waning. While many schools still encourage the use of TI-83/TI-84/TI-89 models, some are pushing the more recent release, the TI-Nspire CX CAS- whose screen resembles many apps for iPhones and Android phones.

Below are some step-by-step instructions (with pictures) of how to graph equations on a TI-Nspire CX CAS calculator (as shown in the far right image above).

2. Then select option B to GRAPH from the left column. This will display the general graphing screen (with any previous graphs of equations/functions reloaded)

3. Tap the “tab” button to load the function editor. This is similar to pressing the “Y=” button on the TI-83 line of calculators.
