Also, Sin 2x = $\frac{2tanx}{1\tan 2x}$ To Prove Sin2x in the form of tanx x which is equal to $\frac{2tanx}{1\tan 2x}$ Now let us start the proof from theTan(2x) = 2tanx/(1 tan2x) So tan(2x) 1 = 2tanx/(1 tan2x) 1 = 2tanx/(1 tan2x) (1 tan2x)/(1 tan2x) = (tan2x 2tanx 1)/(1 tan2x)Solve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and more
