Is there a general method for this?(adsbygoogle = window.adsbygoogle || []).push({});

I remember in complex analysis going the other direction; that is, a function of z becoming a function of x and y.

But I need to turn a complex function in a function of just z, for the purpose of integrating with respect to z.

In particular, the function is

x^2/2-cx-y^2/2+ i(x-c)y where c is a constant.
