This needs to be integrated: 1/(e^(2x) + e^(x)) w/respect to x Can't do partial fractions because e^x never equals zero. Right? Any suggesions? Thanks, JN

I would go ahead and write it this way: Now, it shouldn't be too bad. The other can be done with a simple u sub:
You may wish to rethink that Partial Fraction idea. I knew there was something wrong with that method of finding Partial Fractions. Have you considered ?

Hey thanks for the input. But it seems that I'm having some sort of mathmatical disconnect here: 1. By factoring: 2. How does this equal ?

Ah dang algebra! Thanks!

Thanks, JN Just remember that if you get stuck you may legally do the following Let So that Now let Multiplying through by we get Now letting we get and letting we see that so we see that now back subbing we see that and just to finish it
