Degrees (angle) Converts angle units from radians into degrees.
Radians (angle) Converts angle units from degrees into radians.
Cos (angle) Returns the cosine of a given angle in degrees.
Sin (angle) Returns the sine of a given angle in degrees.
Tan (angle) Returns the tangent of a given angle in degrees.
Acos (number) Returns the arc-cosine (in degrees, from 0 to 180) of a given number.
Asin (number) Returns the arcsine (in degrees, from -90 to 90) of a given number.
Atan (number) Returns the arctangent (in degrees, from -90 to 90) of a given number.
Atan2 (X, Y) Returns the arctangent of y/x, using the signs of both arguments to determine the quadrant of the return value. The returned angle is given in degrees within the range 180 to -180.
