Hey guys, is it just me or are there a lot of questions on the trig sub webwork that require partial fraction decomposition(like problem 10 and 11)? I’m not really sure how to do those two without partial fraction decomposition being as there’s no radical in the problem.

Due to t not being a real # when t > 1, this integral is invalid because there cannot be negative under the radical.
