Category: Trigonometric

Syntax: `Radians ( angleInDegrees )`

Parameters:

angleInDegreesA number representing an angle measured in degrees.

Data type returned: Number

Description:

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

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 2xPi radians in 360°.

Examples:

Function	Results
`Radians (60)`	Returns `1.0471975511965977` (= Pi/3).
`Radians (180)`	Returns `3.1415926535897932` (= Pi).
