Two problems in this question, the first I was able to do but was getting an incorrect answer and the second I'm just plain stumped on.
Here is what I've done so far... I'm coming close but my numbers aren't quite right.
...and subbing in just leaves me with the wrong answer. Where did I go wrong?
Thought to use or , but neither really panned out
Thanks in advance.
Can't believe I made that mistake... I was thinking of the integral and not derivative. My class isn't up to the Weierstrass substitution yet. Also, I find it funny that a proof for the integral of csc(x) I was viewing stated that the strategy was not obvious... oi!
Thanks for the help.
