Anyway the equation was:

**\(\displaystyle sin(3x) + cos(x) = 0\)**

And it asked you to find the general form of the solution...

I have tried compound, double angle formulas but to no avail. I can graph it and find some solutions but not how to find a general form equation? Can someone please shoe me how to solve it?

Cheers
