@AmTran_Bus Try it and tell me what you get ?

I kept getting it to equal sin2. Let me give it another try.

No if you try to reduce it,It will come to
\[ \sin^2x -\cos^2x \]

Then put it in the actual ques.
\[\sin^2x- \cos^2x + 2\cos^2x = 1\]

Now you know how it goes ? @AmTran_Bus

I understand that, yes. But maybe I just can't see it because I can't carry it on.
