ArcTan- Returns the arctangent of a number
Function that returns the arctangent of a number, angle expressed in radians.
- ArcTan(X): float
Parameters:
- (float) X: tangent for which to get the angle.
Description:
Use the ArcTan function to derive the arctangent of a number, an angle expressed in radians. This instruction is a trigonometric function, inverse of the tangent function (Tan) and having as values the angles expressed in radians. The resulting angle is expressed in radians with a value between -PiGreek/2 and PiGreek/2.
To express the arc tangent in degrees, multiply the result by 180/PiGreek.
