1. Trig question
Hey guys,

I was wondering if you could explain this question to me
solve the equation cos2x= the squarerootof 3 sin2x

if i bring sin 2x under cos2x to get tan2x

so the new equation would be tan2x= squareroot of 3 would it not?

I was thinking that as well but the answers says tan2x= 1/ square root of 3.

Divide both sides by

I don't understand why are you getting confused at such a simple thing.
