okay thank you

okay, so what do you mean by a trig identity?

The actual given identity is what I posted in the title and first thing in the thread

Hi, I need help proving the following trig identity, (2sinx)\overline{secxtan(2x)}=2cos^2x-csc^2x+cot^2x I have tried starting from the left hand side, the right hand side, and doing both together, but nothing seems to work. One of the ways I tried: LHS...

Hi, I need help proving the following trig identity: $$\frac{\cot^2(x)-\cot(x)+1}{1-2\tan(x)+\tan^2(x)}=\frac{1+\cot^2(x)}{1+\tan^2(x)}$$ Me and my friend have spent several hours determined to figure this out, starting from the left hand side, the right hand side, and doing both together...
