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

sin^{2}x + cos^{2}x = 1

but would sin^{2}3x + cos^{2}3x = 1?

2. Relevant equations

none.

3. The attempt at a solution

I'm pretty sure sin^{2}3x + cos^{2}3x cant equal 1 otherwise the identity would probably be written as sin^{2}cx + cos^{2}cx = 1 and i've never seen it written like this.

I was doing a homework problem and i ended up in a situation where, if i could use sin^{2}cx + cos^{2}cx = 1, i'd get my answer. But im doing it differently than the book, so my way might be wrong
