Hello Everyone,

I'm trying to figure out how to simplify the following. I'm trying to solve it but I'm not getting any of my answer choices. If someone could give me one example for only one I believe I could figure out the other ones.

My attempt:

= $\displaystyle Cos^2(x)(tan^2(x))$ = $\displaystyle \frac{adj^2}{hyp^2} \cdot \frac{opp^2}{adj^2} = sin^2(x)$

= $\displaystyle \frac{sin^2(x)}{cos(x)}$ STUCK

= $\displaystyle \frac{tan^2(x)}{sin^2(x)} = csc^2(x)$ <- Is there any other way to rewrite this? Is not in one of my choices

= $\displaystyle csc(x)$
