Hi, I'm gonna take this class called "Applied analysis" text semester and I want to be sure that I have more than one reference book, so I need to know what are the books on this subject so I can borrow them at the library before anyone else. This class will talk about: Beta and Gamma functions. Fourier series and other orthogonal functions. Sturm-Liouville's problem. Approximation in quadratic mean. Separation of variables for partial diff. equ. Fourier and Laplace transforms. thx!
