integrate sec^2(3x)(e^(tan3x))

tan3x=(3tanx-tan^3x)/(1-3tan^2x)

1. If f(x)=tan3x, find f'(x) and f'(3). 2. let f(x)=3cos(cosx), find f'(x). i got stuck. i do...

integrate by parts integrate (4+x^2)^1/2

solve 2tanx cos2x+1=tan3x+2cos2x

Prove that tan3x-tan2x-tanx=tan3xtan2xtanx

Find domain of tanx/tan3x

tan3x= radical3 / 3

tan3x tan2x tanx = tan3x - tan2x-tanx

tan3x tan2x tanx = tan3x - tan2x-tanx proof that

tan3x tan2x tanx = tan3x - tan2x-tanx proof that very easy
