The calculator has three setting options for the angular mode for use with trigonometric functions:
Degrees: A circle is divided into 360 degrees (360°).
Radians: The circumference of a circle is 2π radians.
Grades: There are 400 gradians (400 g) in a circle.
The angular mode affects functions like sine (SIN), cosine (COS), tangent (TAN) and other associated trigonometric functions. To change the angular mode, use the following procedure:
To select the desired mode, either:
