Prove the identity 1+tan^2x/2tanx=csc2x
Prove the identity 1+tan^2x/2tanx=csc2x-2 x 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't do that, but something was wrong Anyways I looked at the solutions manual and they magic out 1 tan x tan 2 x = 1 tanI just want to ask The equation says tan2x=2tanx/1tan^2x How did it become 2tanx and 1tan^2x?

I know that and The next step would then be to say that but now what?1 sin 2x = 1 sin 2x (Pythagorean identity) Therefore, 1 sin 2x = 1 sin 2x, is verifiable HalfAngle Identities The alternative form of doubleangle identities are the halfangle identities Sine • To achieve the identity for sine, we start by using a doubleangle identityThese identities are useful whenever expressions involving trigonometric functions need to be simplified An important application is the integration of nontrigonometric functions a common technique involves first using the substitution rule with a trigonometric function, and then simplifying the resulting integral with a trigonometric identity
