Hello, I'm trying to solve a PDE using a Exp ansatz. Now I am am stuck with the equation of the form a Exp[I k x] + b Exp[I k x] == 0 (though much more complicated) What I would like to do is a comparison of coefficients. How can I make Mathemetica to show me a form of the equation where I can easily read the comparison equations? (In the above equation (a + b) Exp[I k x] == 0 for example.) Regards Kay-Michael Voit
