# Seperation of variables - first order PDE

[SOLVED] Seperation of variables - first order PDE

1. Homework Statement

I have the expression X'(x)/X(x) = cx. How do I seperate the variables? It's the fraction on the left side that annoys me.

I know that X'(x) = d(X(x))/dx, but I can't use this here?

EDIT: Sorry for the mis-spelled title. It's "separation".
