Excel's trig functions can be used to find the sine, cosine, and tangent of an angle. These tutorials include step by step examples of using Excel's trig functions.
Excel SIN Function
The SIN function gives you the sine of an angle measured in radians.
Excel COS Function
The COS function gives you the cosine of an angle measured in radians.
Excel TAN Function
The TAN function gives you the tangent of an angle measured in radians.
Excel RADIANS Function
Excel's, trig functions use angles measured in radians not degrees. The RADIANS function converts angles measured in degrees to radians.
Excel DEGREES Function
The DEGREES function converts angles measured in radians to degrees.
