I am currently working on a practice problem on trig substitution.
I have no problem solving it my way but I don’t see how i can use the below stated identity and partial integration. (I am sorry i am not using mathjax, im looking into it but it is quite confusing for me)
I tried rewriting as 1- sin^2(theta), but when i attempt to use partial integration it just does not solve, and I have no idea how to rewrite it.
Many thanks for your help
