Solution 11790: Step-by-Step Functionality on TI Graphing Calculators.
Which of the graphing calculators have step-by-step functionality?
Currently, TI graphing calculators do not offer step-by-step functionality. However, there is an Application (App) called Symbolic Math Guide (SMG) available on the TI-89 family, TI-92 Plus and Voyage™ 200. This App allows the user to choose the steps that must be performed in order to solve a problem.
For more information on the functionality on graphing calculators, please refer to the available guidebooks.
