Compute the inverse tangent of a number and return a result in degrees

ResourceFunction["ArcTanDegree"][x]

computes the inverse tangent of x in degrees.

Details and Options

ArcTanDegree is a mathematical function, suitable for both symbolic and numerical manipulation.
ArcTanDegree[x] always returns a value between -90 and 90.
For certain special arguments, ArcTanDegree automatically evaluates to exact values.
ArcTanDegree can be evaluated to arbitrary numerical precision.
ArcTanDegree automatically threads over lists.

Examples
