I have a known complex number ** c** and a known complex number

**.**

*d*I need to find the complex number ** x** that gives

**when multiplied by**

*d***.**

*c*I want to find this number ** x** using

**and**

*c***. What is the equation for finding**

*d***using the known values**

*x***and**

*c***?**

*d*The reason I need this is because I am writing a graphics program that needs to scale and rotate an arbitrary set of complex numbers (using multiplication) so that the set conforms to a desired space in the complex plane.

Thanks!
