If the angles are doubled, then the trigonometric identities for sin, cos and tan are sin 2θ = 2 sinθ cosθ;I need to prove that $$1\tan x \tan 2x = \sec 2x$$ I started this by making sec 1/cos and using the double angle identity for that and it didn't work at all in any way ever Not sure why I can'Legend x and y are independent variables, ;
