Best ResponseYou've already chosen the best response.0you know that when the numerator is the derivative of the dominator then the integration is ln "dominator" :)

Best ResponseYou've already chosen the best response.0ok , the derivative of (x^2 )^1/2 is 1/2 (2x) so 2 cancel the other 2 :)

Best ResponseYou've already chosen the best response.0yeah but we can't multiply it with 2x so ln(1+x²)½ is not the right answer

Best ResponseYou've already chosen the best response.0by backward substitution \[\tan \theta =x\]

Best ResponseYou've already chosen the best response.0yeah that will give us integration of secθ that is ln(secθ+tanθ) and by substituting and we will get probably get ln(sec(tan^x)+x)
