Web$\begingroup$ The problem I am getting at is that any method for finding these partial derivatives that uses inverse trig functions is invalid for certain critical $\theta$. Since you are using $\arctan$, this method will not be valid for $\theta$ crossing over from say $\pi-\epsilon$ to $\pi+\epsilon$. And yet partial derivatives of $\theta$ when $\theta=\pi$ … WebDec 4, 2015 · x^2+y^2=x Multiply both sides by r: r^2=rcos(theta) Use the formulas r^2=x^2+y^2 and x=rcos(theta): x^2+y^2=x.

WebSubstituting r(cos θ + i sin θ) for e ix and equating real and imaginary parts in this formula gives dr / dx = 0 and dθ / dx = 1. Thus, r is a constant, and θ is x + C for some constant C. The initial values r(0) = 1 and θ(0) = 0 come from e 0i = 1, giving r = 1 and θ = x. This proves the formula
