Math Menu Functions on the TI-84 Plus Calculator

Most functions housed in the TI-84 Plus calculator's Math menu require that the argument be entered after entering the function. Such functions are easily recognizable by the parenthesis following the name of the function.

With one exception, functions in the Math menu that have no parenthesis at the end of their names require that the argument be entered before the function is entered. The cube function is an example of such a function. (The exception is the xth root function,

This function requires that the root be entered first, then the

function, and then the argument.)

Math menu functions are usually inserted into arithmetic expressions entered on the Home screen, or into definitions of functions in the Y= editor. Pressing [2nd][MODE] puts you in the Home screen, and pressing [Y=] puts you in the Y= editor. The Y= editor is used to define functions you want to graph.

To insert a Math menu function into an expression, follow these steps:

1. If necessary, use

   

   to place the cursor where you want to insert the function.

   Inserting a Math menu item in an arithmetic expression that is entered on the Home screen is illustrated here. This figure shows how to insert the cube function in order to evaluate

   

2. Press [MATH].

3. Use

   

   to select the appropriate submenu of the Math menu.

4. Enter the number of the function or use

   

   to highlight the number of the function and then press [ENTER].
