Hello all, I just bought the book "Advanced Mathematical Methods for Scientists and Engineers - Asymptotic Methods and Perturbation Theory". I was wondering if anyone know about a solutions manual for the book? I would like to work through some of the problems while I go through the book, but it would make it a bit more easy to have a reference, to see if I solve the problems correctly. I haven't been able to find anything so far on the web. How do you go about solving problems in a textbook without a solutions reference?
