ATAN(expression)

ATAN

Returns inverse tangent.

expression

A numeric constant, variable, or expression for the value of the tangent.

The ATAN procedure returns the inverse tangent. The inverse of a tangent is the angle that produces the tangent. The return value is the angle in radians. p is a constant which represents the ratio of the circumference and radius of a circle. There are 2p radians (or 360 degrees) in a circle.
