Simplify this function

**dsuh2010** · April 17th 2009, 12:57 PM

Should be a good brain refresher!

$<br /> {4-4\cos^2(x) \cdot \left(1-\frac{1}{\left(\csc^2(x)\right)}\right)^2}+(cot^2( 2x))\frac{(1-2\sin^2(x))^2}{\frac{1}{\frac{1+\cos(2x)}{\cos(2x) }\cdot \frac{1-\cos(2x)}{\cos(2x)}}}<br />$
The answer should come out to a really nice answer if I did my math right........ After a lot of editing, I hope this comes to the right answer (many mistakes)
THIS IS THE FINALIZED AND EDITED PROBLEM.

Hi,

I'm rewriting it in correct latex, because the way you wrote it is not easy to decipher

Tell me if it's correct.

$\frac{1}{\sqrt{4-4\cos^2(x)} \cdot \left(1-\left(\frac{2}{\sec^2(x)}\right)^2\right)}+\frac{1-2\sin^2(2x)}{\frac{1+\cos(2x)}{\cos(2x)}}\cdot \frac{1-\cos(2x)}{\cos(2x)}$
