I set u=sqrt(1-u^2) (du=-u/sqrt(1-u^2) and dv=du, so that v=u. But this didn't help much, since I still need in integrate sqrt. (1-u^2). It started to look more like inverse sine though.
Yeah, I thought about it, and it works out with a/b being the slope of the asymptote. But different sources stick to either a/b and b/a, so it's really confusing which slope is actually correct.
Hey! Can somebody take a look on these two limit problems? I don't agree with the answer to #15, which is supposed to be 0 while I get infinity. #16 seems to ask to find the value of the sum...I posted a pic of my attempts to solve the problems below.
