ok, the domain of tan for which arctan exists (conventionally) is (-pi/2 , pi/2) -- really the domain of tan is R, but we're using the restricted one.

Optimisation and implementation of the arctan function for the power.
Take partial derivatives: u_x = (y/x^2) / (1 + (y/x)^2) = y/(x^2 + y^2) u_y = (-1/x)/(1 + (y/x)^2) = -x/(x^2 + y^2). So, u_xx = -2xy/(x^2 + y^2) and u_yy.
Since the domain of arctan(x) is all real numbers, the only exclusions come from the values of t we discarded earlier, t = ±π. 4. Since x = tan(t), this means we.
