Hello all, I realize this isn't exactly the correct place to post this, but I can't start a thread in the mathematics learning forum, I'm not sure if I am supposed to be able to or not. I realized that I threw away one of my instructors math books on Fourier Theory I was borrowing over the summer on accident (I took out the wrong box and lost a number of my books as well), and I need to find the same one. It was a book on Fourier Series and Transform theory, from awhile ago--perhaps 70s. It was light blue and pink on the cover, kind of dated graphics, and was a paperback--and that is unfortunately all I know about it. My professor is all about pure mathematics, rather than applied, and this book very likely followed that trend. I've combed through a few publisher sites, half.com, Google images etc hoping to run across it but I haven't seen it yet. I'm not only missing out on the book, but I'd hate to get back to school and have to ask him about it so I could replace it then (he's off campus for the summer). If this book rings any bells, please let me know! Thank you, and I know this is pretty lame, but I want to fix it as soon as possible.
