# Thread: Help with Trig. Identity Problem

1. ## Help with Trig. Identity Problem

Hey guys, can't seem to figure out the below problem. Any help is greatly appreciated.

2. ## Re: Help with Trig. Identity Problem

common denominator on the left side ...

$\dfrac{2\sin{x}\cos^2{x}-\sin{x}(\cos^2{x}-\sin^2{x})}{\sin{x}\cos{x}}$

change both $\cos^2{x}$ to $(1-\sin^2{x})$ in the numerator ... then simplify the numerator.

Thank you! Not sure why I couldn't figure that out...
