A lot of questions say use polar coordinates to calculate limits when they approach $0$. I'm trying to evaluate the following definite integral but am unsure how to handle the absolute value efficiently over the given interval. I see now how i can go about evaluating the limit itself although i still find the concept a little bit vague, as in considering a.
