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-10.5 = 30
