There are two integrals that I don't know how to solve. I'm fairly certain the preceding work that led me to these integrals is correct.
1. ∫sin (x) / (csc (x) + cot (x))
2. ∫x^(2) / (1 - x)
The Attempt at a Solution
U substitution didn't work for either integral. Is integration by parts the correct way to go?
