We know that tan2x=sin2xcos2x. Therefore, we can rewrite the expression using this identity. 2. Rewrite the Expression: The expression can be rewritten as: 1+tan2x1−tan2x=1+sin2xcos2x1−sin2xcos2x=cos2x+sin2xcos2xcos2x−sin2xcos2x=1cos2x−sin2x since sin2x+cos2x=1. 3. ...
tan 3(2x)sec(2x)dx -[m'(2)[:m(2x)(2)] Recall the identity: tan 2(2x)=sec 2(2x)-1) = ∫ [ sec^2(2x)-1 ] 1/2d [ sec(2x) ] (Let u=sec(2x) = ∫ (u^2-1)/2du = (u^3)/6- u/2+C (Replace u with sec(2x)) = (sec^3(2x))/6- (sec(2x))/2+C ...
