numpy.arctan()

numpy.arctan

numpy.arctan(x[, out]) =

Trigonometric inverse tangent, element-wise.

The inverse of tan, so that if y = tan(x) then x = arctan(y).

Parameters:

x : array_like

Input values. arctan is applied to each element of x.

Returns:

out : ndarray

Out has the same shape as x. Its real part is in [-pi/2, pi/2] (arctan(+/-inf) returns +/-pi/2
