I'm three weeks into my Calculus II semester and we've just finished covering derivatives and integrals of [itex]ln[/itex] and [itex]e^x[/itex]. We haven't had the first test yet, which will be covering this material.
Things that trip me up are some of the tricky u-substitution methods, change of form, etc., or one in particular is: [itex]\int\frac{2x}{(x-1)^2}dx[/itex]
A couple of classmates were working together the other day and the way one was showed to work this problem out was by changing the numerator to [itex]2(x-1)+2[/itex] which is essentially [itex]2x[/itex]. The thing that gets me about this is, I have no idea how to look at that example and know that I need to perform that change of form, my mind doesn't even see that.
Mostly I feel like I'm getting the calculus concepts, aside from what I've mentioned above, however I have always been a bit shaky with algebraic skills. It seems most of my mistakes come from making "simple" errors or not seeing ways of simplifying something that would be obvious to someone with a more solid understanding of algebra.
It's an odd feeling. If I know what problems I'm having, it should be easy to go back to certain topics in algebra and build up on them, but it hasn't worked out that way when I try it.
I thought someone might have the right tip for me, maybe trying something different will help me progress a little easer. Until then, I'll keep working examples, as that's the only thing I know to do to get better at these.
