4. Using the Math Input/Output Mode

Selecting “Math” for the “Input/Output” mode setting on the Setup screen (page 1-32) turns on the Math input/output mode, which allows natural input and display of certain functions, just as they appear in your textbook.

The operations in this section all are performed in the Math input/output mode. The initial default setting for this calculator is the Math input/output mode. If you have changed to the Linear input/output mode, switch back to the Math input/output mode before performing the operations in this section. See “Using the Setup Screen” (page 1-32) for information about how to switch modes.

In the Math input/output mode, all input is insert mode (not overwrite mode) input. Note that the !D(INS) operation (page 1-7) you use in the Linear input/output mode to switch to insert mode input performs a completely different function in the Math input/output mode. For more information, see “Using Values and Expressions as Arguments” (page 1-17).

Unless specifically stated otherwise, all operations in this section are performed in the Run-Matrixmode.
