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

[tex]sin6x+sin4x=0[/tex]

2. Relevant equations

[tex]sinx=2sin\frac{x}{2}cos\frac{x}{2}[/tex]

[tex]sin2x=2sinxcosx[/tex]

[tex]cos2x=cos^2x-sin^x[/tex]

3. The attempt at a solution

[tex]2sin3xcos3x+2sin2xcos2x=0[/tex]

[tex]sin3xcos3x+sin2xcos2x=0[/tex]

What shall I do next?
