Trigonometric and Inverse Trigonometric
Functions
The angle unit required by trigonometric and inverse
trigonometric functions is one specified as the calculator’s
default angle unit. Before performing a calculation, be sure to
specify the default angle unit you want to use. See “Specifying
the Default Angle Unit” for more information.
Example: sin 30 = 0.5, sin
