The equation

2%2Atan%28x%29-sin%282x%29%2F2sin%28x%29%5E2=tan%28x%29

is not an identity.

Sorry to be picky....

But if your studies of math have progressed to the point where you are proving trig identities, then you should know by now that sometimes parentheses are required to make things right.

Re-post, showing the correct identity.
