Degrees to Radians

The .Net Framework uses by default radians in its trigonometry calculations. Find out how to convert degrees to radians to use with C#

private double DegreeToRadian(double angle)
{
return Math.PI * angle / 180.0;
}

//Get the Cosine of a 45 degree angle
double angle = Math.Cos(DegreeToRadian(45));

What about 45°30'10''?
Angles don't always come in whole parts.

If the angle isn't whole use a decimal point (45.352343). If you want to convert something like 45°30'10'' to a decimal representation then that would be a different function to write.

It gives an error because tan(90) is undefined.
