The TI-84 Plus Calculator Catalog

The TI-84 Plus calculator’s Catalog houses every command and function used by the calculator. However, it’s usually 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 the


    keys 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][O] to enter the Catalog.

    This is illustrated in the first screen.

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

    Notice that the calculator is already in Alpha mode, as is indicated by the reversed A in the upper-right part of the screen. 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 function seq(, press [LN] because the letter S is written in green above this key. Use the down-arrow key to scroll down to seq(.

  4. Repeatedly press the down-arrow key to move the indicator to the desired command or function.

  5. (Optional) Press [+] to access Catalog Help for the listed command or function.

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

  6. Press e to select the command or function.

    After pressing [ENTER], the command or function is inserted at the cursor location.
