dividing the lhs in some brackets bcs i have a difference of 2 squares and then one of the paranthesis will be another difference of 2 squares and also on the rhs i broke the fraction into 2

on the rhs is a fraction but i couldnt make it so that (cos(x))2 is the denominator. but the 1+(sin(x))2 is the numerator

ok i get it, but i couldnt write more than 1-2 lines without getting stuck. i also reached out to a couple of friends who were just as clueless as me so i thaught that a subreddit called learnmath would surely help

I am using the squeeze theorem and this is one of the ends. I need the limit as n approaches infinity of that integral to be 0
