Let P(z) be the werierstrass elliptic function with periods w_{1 }and w_{2.}How to estimate the partial derivative of |P'(z)| with respect to x? where z=x+iy.

Thanks!

Hey margar.

Recall that the magnitude of a complex vector is |z| = SQRT(x^2 + y^2) and d|z|/dx = x/SQRT(x^2 + y^2).

Now consider z being a function of a complex variable.
