Radians()

Category: Trigonometric

Syntax: Radians ( number )

Parameters: number ”A number representing an angle measured in degrees.

Description: The Radians() function converts an angle measured in degrees into an angle measured in radians.

Examples:

Radians (60)

Returns 1.0471975511965977 ( = Pi / 3).

Radians (180)

Returns 3.1415926535897932 ( = Pi).

Comments:

The trigonometric functions Sin() , Cos() , and Tan() all take an angle measured in radians as their parameter. To find, say, the cosine of a 180 ° angle, you could use the formula Cos ( Radians (180)) . There are 2 x Pi radians in 360 °.
