Homework Help: Trig

Posted by Janie on Sunday, January 24, 2010 at 7:04pm.

2cos^2Beta-Cosbeta=0 (find all solutions for the equation in the interval 0, 2 pi). I have no idea how to go about doing this. Do you isolate the beta on one side? Would you be able to show me how and I'll solve for you to check?
