1.) sin(adsbygoogle = window.adsbygoogle || []).push({}); ^{2}x=3cos^{2}

2.) (3tan^{2}x-1)(tan^{2}x-3)=0

3.) cos^{3}x=cosx

4.) 3tan^{3}x=tanx

Those were a few of the problems in the section I missed on friday due to illness and I was wondering if anyone could walk me through them. Would be greatly appreciated!

They want to solve the equation for 0<=x<2pie for #1 and #2.

and

Find all solutions of the equation in the interval [0,2pie) algebraically for #3 and #4.

Oh and could anyone tell me how to make the symbols for pie, square root, and greater than or equal to for future reference?
