For me, you gave three super important tips. 1. where e came from, (which someone else mentioned), 2. Keeping u consistent, ("if you make u the trig function, keep it the trig function"), and 3. how you get the original function in the end and have to cancel it out to get the final answer. thanks a lot for the well-explained procedure.

Thank you for being the first fucking person that actually explained where the e came from.. Searched for ages to find it but nope no luck. No explanation from the teacher. Nothing.
