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 you

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))
