### Math Functions

One-Number Functions
Math functions involving one number use the number in the display. To execute one-number
functions, with a number displayed, press the key or key combination corresponding to the
operation you wish to execute. The result is displayed. See Table 2- 1 4 for a list of one-number
functions.
Before doing any trigonometric calculations, check whether the angle mode is set for degrees
or radians (Rad). Degrees is the default setting. The RAD annunciator in the display indicates
radians is active. Press
