# Excel's Trig Functions

Excel's list of functions includes the common Trig functions that can be used to find the sine, cosine, and tangent of an angle.

Since Excel's, trig functions use radians, we often need a way of converting angles measured in degrees to radians. The RADIANS function, one of Excel's math functions, does just that.
