COSINE()

COSINE() returns the numeric cosine of an angle that is expressed in radians.

Function Format

COSINE(radians)

COSINE() returns the numeric cosine of the measurement of the desired angle in radians.

Note: If your angle is expressed in degrees, use the RADIAN() function to convert the degrees to radians. To round the result of the RADIAN() function, use the DECIMALS() function.

Examples

COSINE(.7854) = 0.707105482511236

COSINE(DECIMALS(RADIANS(45),4))= 0.707105482511236
