Homework Help: Math - Solving Trig Equations

Posted by Anonymous on Wednesday, November 21, 2007 at 6:29pm.

Solve each equation for 0 is less than and equal to "x" is less than and equal to 360


3sinx = 2cos^{2}x

-----



I don't know how to solve this equation...this is what I have, but I don't know if I'm on the right track or not

3sinx = 1 - 2sin^{2}x
3sinx - 1 + 2sin^{2}x = 0
2sin^{2}x + 3sinx - 1 = 0
sinx(3 + 2sinx) = 1

...and if I am, what do I do next now?

The answers are:
30 and 150 degrees
