Heya everyone.
Sorry for this entirely unrelated question, but i'm totally stumped and google isn't helping. I've got a maths assignment for school where we have to integrate some functions, and i'm trying to integrate ln(x+b), but i can't get it to work. I've got it to the point where i have it being equal to xln(x+b) - the integral of x/(x+b), but i can't find how to integrate two functions multiplied together anywhere. I've tried partial integration, but all i did was get more out of my league with x^2/(2x^2+4x+2) which is even worse than before.
I figure that all you programmer types out there did some decent level of maths, and might be willing to help me out. Thanks if you can, otherwise i'll just have to quote a formula, which is nowhere near as fun.
