It is a function which maps the tangent ratio - any real value - to an angle in the range (-pi/2, pi/2) radians. Or (-90, 90) degrees.
If tan(x) = y then x is the inverse tangent of y.
It is also known as "arc tangent", and spreadsheets, such as Excel, use "atan" for this function.
Warning:
1/tangent = cotangent is the reciprocal, NOT the inverse.
