How to Use the TI-83 Plus Catalog - dummies

By C. C. Edwards

The TI-83 Plus calculator’s Catalog houses every command and function used by the calculator. However, it’s easier to use the keyboard and the menus to access these commands and functions than it is to use the Catalog. There are several exceptions; for example, the hyperbolic functions are found only in the Catalog. If you have to use the Catalog, here’s how to do it:

  1. If necessary, use


    to place the cursor at the location where you want to insert a command or function found in the Catalog.

    The command or function is usually inserted on the Home screen, or in the Y= editor when you’re defining a function you plan to graph.

  2. Press [2nd][0] to enter the Catalog.

    This is illustrated in the first picture.

  3. Enter the first letter in the name of the command or function.

    Notice that the calculator is already in Alpha Mode. To enter the letter, all you have to do is press the key corresponding to that letter. For example, if you’re using the Catalog to access the hyperbolic function tanh, press [4] because the letter T is written in green above this key. This is illustrated in the second picture.

  4. Repeatedly press


    to move the indicator to the desired command or function.

  5. Press [ENTER] to select the command or function.

    This is illustrated in the third picture. After pressing [ENTER], the command or function is inserted at the cursor location.
