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.

Excel's RADIANS Function
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.

Excel DEGREES Function
The DEGREES function in Excel converts angles measured in radians to degrees. This article includes a step by step example.

Find the Cosine of an Angle
The COS function can be used to find the cosine of an angle measured in radians.

Find the Sine of an Angle
The SIN function can be used to find the sine of an angle measured in radians.

Find the Tangent of an Angle
The TAN function can be used to find the tangent of an angle measured in radians.
