Sadly Mathematica is not willing to tell this straight away: Simplify@Element[ArcTan[9]/Pi, Rationals] stays unevaluated, which could indicate Mma doesn't know if it's rational or … how to write mathematical expressions in python ArcTan is the inverse tangent function. For a real number x, ArcTan [x] represents the radian angle measure such that . The two-argument form ArcTan [x, y] represents the arc tangent of y / x, taking into account the quadrant in which the point lies.
