Homework Help: Trigonometry

Posted by Anonymous on Sunday, January 3, 2010 at 1:39pm.

How do you know when to add k(2pi) or k(pi)? What's the difference?

Also, for this problem, why are you supposed to use k(2pi/5) for the solutions, assuming that there is no domain?
2sin^2(5x)+sin(5x)-1=0

Thank you!
