## Inverse Tangent — from Wolfram MathWorld

mathworld.wolfram.com19/11/2020 · The principal value of the inverse tangent is implemented as ArcTan[z] in the Wolfram Language. In the GNU C library, it is implemented as atan ( double x ). The inverse tangent is a multivalued function and hence requires a branch cut in the complex plane , which the Wolfram Language ‘s convention places at and .

community.wolfram.comThere should be a saddle pt at (x=-1, y=0), but due to restriction’s in ArcTan‘s argument, there is a cutoff. This problem also affects the dynamics of this field as well because Mathematica just doesn’t recognize that there is overlap between the two Gaussian hills.

## atan2 – Wikipedia

en.wikipedia.orgIn Mathematica, the form ArcTan[x, y] is used where the one parameter form supplies the normal arctangent (note that the order of arguments is reversed relative to the convention used in the discussion above). Mathematica classifies ArcTan[0, 0] as an indeterminate expression.
