(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(tan^{2}x) - (sin^{2}x) = (tan^{2}x)(sin^{2}x)

Prove these two are equal.

2. Relevant equations

Various trig identities, mainly tan^{2}x = sin^{2}x / cos^{2}x

3. The attempt at a solution

I tried putting in Sin^{2}x / cos^{2}x for tan, but I don't know where to go from there.

Anyone mind helping me out?
