I've skimmed a few topics in the Calculus forum, but they haven't turned up answers, and I can't really read anything what with all the [tex] notation. So, maybe this way will work.

In some differential equations I've been working on, I found integrals like 1/(exp(x)+1) and 1/(x+x^2), which I apparently forgot how to solve since high school. I racked my brain about substitutions, but I'm only good at getting stuff to cancel out, and without nice numerators, I'm stumped.

Any help is appreciated (especially regarding how to read what you guys respond with).
