Inverse Tangent in excel formulae
 

How do i use the inverse tangent in an excel formulae? I need to use it to
calculate the distances of a data set.

Inverse Tangent in excel formulae
 

=DEGREES(ATAN(A1)) if you want arctan with one argument.
=DEGREES(ATAN2(A1,B1)) if you want the version with 2 arguments to resolve
the ambiguity of quadrants.
Obviously you can omit the DEGREES() function if you want your answer in
radians.
