How Do You Prove The Identity Tan 2x Secx 1 1 Cosx Cosx Socratic
An alternative method is to take `sec^2 x ` and replace it by `1/(cos^2 x)` Replace `1/(cos^2 x)` by `1 tan^2 x` (the basic formula of trigonometry `1tan^2 x = 1/(cos^2 x)` )In the formula of ta(AB) put A=B=x tan(AB)=(tanAtanB)/(1tanAtanB) So tan(2x)=2tanx/(1(tanx)^2) Hope that it helps · Solve for x tan1 (2x/1x2) cot1 (1x2/2x) = π/3;
