I know this equation uses double angle identities but I don't know where to start on it. Do I expand the sin(2x) or bring it over to the other side of the equation? I know how to solve for x with k values but I don't know how to get up to that point.
cos^4(x)-sin^4(x)=sqrt(3)sin(2x)
Thanks for any help you are able to give.
Factorize
cos4(x) - sin4(x)
and simplify...
