im supposed to integrate this but im not sure how.
∫▒〖sinx/(1+〖cos〗^2 x) dx〗. not sure if it showed up right or not, its supposed to read as the integral of sin x/(1 + cos^2 (x)). i thought about using the double angle identities but i still couldn't get rid of the sin x in the numerator. thx in advance.
