Dear viewersHere , we are going to learn derivation for tan(2x)= 2tanx/1tan²x #subscribe_plz#prooffortan2xDo like, comments and Subscribe for more!!! So I'll have to use a formula From what I know about the graph of the tangent , I know that the tangent will equal 1 at 45° after every 180° These solutions for tan( x /2) are at 0° 45°, 180° 45°, 360° 45° , and so forth For the question, tan(2x)tanx = 1, I divided it by tanx, and got the solution as (2n 1) π 6 tan2x = cotx = tan(π 2 − x) So, 2x = nπ π 2 − x So, 3x = (2n 1) πSin(2x) = (2tan(x)) / (1tan^2(x)) *** Start with RHS 2tanx/(1tan^2x) 2tanx/(sec^2x) 2(sinx/cosx)/(1
