Best ResponseYou've already chosen the best response.2this one is a little bit hard to get...at least for me but i'll do it with \[x=\frac{2}{\cos \theta}\]with \(0<\theta<\pi\)

Best ResponseYou've already chosen the best response.1oh ... i didn't realize \[ \frac{2 ( \sqrt{x+ 2})^2}{\sqrt{x+2}\sqrt{x2}}= \frac{2 \sqrt{x+2}}{\sqrt{x2}}\] there isn't asymptotic behaviour at x=2

Best ResponseYou've already chosen the best response.1the  infinity part is always confusing, don't cancel .... for that. rest is just same as you did.
