When using the trigonometric functions
of the `Math`

class, all units are in radians;
instead, you require a result in degrees.

To convert a value in radians to degrees, multiply it by 180/π:

using System; public static double ConvertRadiansToDegrees(double radians) { double degrees = (180 / Math.PI) * radians; return (degrees); }

All of the static trigonometric methods in the
`Math`

class use radians as their unit of measure
for angles. It is very handy to have conversion routines to convert
between radians and degrees, especially when displaying degrees to a
user is more informative than displaying radians.

The equation for converting radians to degrees is shown here:

degrees = (180 / Math.PI) * radians

The static field `Math.PI`

contains the constant
π.
