2tanx/1 tan^2x=sin2x 255949-2 tan x 1 tan2 x sin 2x Marion Dudley

Sin(2x) = (2tan(x)) / (1tan^2(x)) *** Start with RHS 2tanx/(1tan^2x) 2tanx/(sec^2x) 2(sinx/cosx)/(1 How do you prove tan (2x) = (2tan (x) ) ...

コンプリート！ 2tanx/1 tan^2x=sin2x 346037-Prove that sin2x=(2tanx)/(1+tan^(2)x) Marion Dudley

You can put this solution on YOUR website! 2tanx/(1tan^2x)=sin2x since 2sinx/cosx / sec^2x 2sinx/cosx * cos^2x 2sinx*cosx = sin2x If I garbl...
