 Mar3 accepted Choices for Integrationg by Parts Mar3 comment Choices for Integrationg by Parts Errummm.... that was silly mistake. Ok, that was my problem! Thank you for pointing that out Mike! How could I have missed that? Mar3 comment Choices for Integrationg by Parts If that is the case, then shouldn't the answer come out the be the same, regardless of what (within reason) I pick? Mar3 comment Choices for Integrationg by Parts Thank Mike, but I did use v and du in the integral. Since I used integration by parts twice, maybe that is why it looks as though I had done that. Mar3 asked Choices for Integrationg by Parts Mar2 accepted Methodology for Integration by Parts Mar2 comment Methodology for Integration by Parts Ah... good point, Antonio. Mar2 comment Methodology for Integration by Parts Ah ha! Thank you for answering my second question! I figured that was why they chose $\sin{x}$ over $\sin^{n - 1}{x}$, but I just wanted to be sure that I wasn't missing some mathematical rule. Do you know why they decided to split up $\sin^{n}{x}$ into two terms and then let dv be $\sin{x} \ dx$ rather than the understood 1? Mar2 comment Methodology for Integration by Parts Hmm... yes, but then I would like an explanation as to why the other methods wouldn't work.

Feb24 comment Integrating $\int \sin^n{x} \ dx$ ohhh... then the $(n - 1)$ was distributed when the integral was broken up, I guess that is what was throwing me off. Thanks, Mike!
