Math Tutorial

A professor I know used to tell me about how one of his students submitted every assignment with the inscription "From the laboured desk of X". Well I guess I understand what the student was talking about.
No I am not doing lots of work, just a little more than what I normally do. The reason I feel the way I feel is because I am here, working on a Saturday. Not that it is so bad in itself. But coupled with the fact that I am trying to integrate a huge multipart function which is not, as my professor says, "cleanly integrable" - well. And math, especially calculus is not one of my strong suits. Neither is Matrices, come to think of it, and without these two, I have no business doing anything in engineering. Ok lets not talk about such cold hard facts, let us switch to something warm and fuzzy - like comfort food.
I spent the better part of an hour searching for some site to help me with integration. I found a good PDF guide to some complex integrals. I also found this beautiful tutorial by some blessed instructor -Paul Dawkins - wonderful stuff. I am providing the link here. Yenjay!!
