Ex 33, 23 Prove that tan4𝑥 = (4 tan〖𝑥 (1−tan2𝑥)〗)/(1 − 6 tan2 𝑥tan4 𝑥) Taking LHS tan 4x We know that tan 2x = (2 𝑡𝑎𝑛𝑥)/(1 − 𝑡𝑎𝑛2 𝑥) Replacing x with 2x tan (2 × 2x) = (2 𝑡𝑎𝑛2𝑥)/(1 − 𝑡𝑎𝑛2 2𝑥) tan 4x = (2 𝑡𝑎𝑛2𝑥)/(1 − 𝑡𝑎𝑛2 2𝑥) = (2 taQuestion Prove The Identity Sec^2/2 Tan X = Csc 2x This problem has been solved! the opposite side is $$2tanx=2*2=4$$ the adjacent side is $$1tan^2x=12^2=14=3$$ (the negative sign just means it will not be in the first quad ) Using pythagoras the hypotenuse will be
