Function
I am using the cos() function and it is returning the wrong answer. =cos(22.62) is giving -0.8087 The correct answer is 0.9231. What am I doing wrong here. Any help would be appreciated. Thank y...
All trigonometric functions in Excel use radians as unit of angle, not degrees, where 180 degrees = π radians.
Excel has conversion functions RADIANS and DEGREES.
The formula you want is
=COS(RADIANS(22.62))
