Homework Statement \int^{A}_{-A}\int^{Bx}_{-Bx}c\delta(xcos\varphi+ysin\varphi-d)dydx where A, B, c, d are constant Homework Equations The Attempt at a Solution I have tried a few different ways to integrate this, but am completely confused with what happens to this kind of delta...

Hey thanks for that. I had tried Newton's method, but silly me messed up some simple numbers. :redface: I tried again and paid more attention and it worked. For some reason I thought that Newton's method wouldn't work for an exponential.

Hi. I've been mulling over the problem of how to solve y=e^{ax}+e^{bx} for x. I know it can't be solved numerically and have been trying to think of a way to solve it iteratively. The problem is, I can only find algorithms for polynomials and they don't seem to work for exponential problems...
