Thank you for putting rigorous mathematics at a level where everyone can understand. This is why I nominate you as the best Professor forever. It does not have to be as complicated as some seem to think.

love these series. when I was back in school I always think substitution was kind of difficulty. now I am so aged. love the substitution.

me again 🙈🙈🙈🙈 eheheh today I have two questions
I encountered something I'd never though before it may cause a mistake .. generally about integration by substitution .. here if we let cos^2(theta) = U the process seems to be alright but at the end we end up with -0.25cos^4(theta) why it is not possible to consider cos^2(theta) = U

i wish you broke down the steps at 3:15 more slowly

On the, in the case of Pro. Biezen extremely unlikely, case of an error, thousands of hours might be saved using the saying, sanitized here: stuff happens. I once spent several days finding out that one the slow way. Just sayin'.
