now what values of x cause that to happen?

how would you go about solving

tan2(x) = 8cos^2(x) - cot(x), domain is 0 to 360

please help...

begin by changing everything to sines and cosines and see where you can go from there

hey thanks, but actually i got it a different way, i was doing some simple multiplication wrong. lol. I hate how when you're doing something challenging you tend to undermine the simple stuff. heh.
