i need help with it

solve the equation for the solutions over the interval [0 degrees, 360 degrees) 6sec2xtanx=12tanx I am unsure of where to begin.

cos(3theta)=-1 solve for exact solutions over the interval [0,360 degrees] I am having trouble finding a place to start.

I am getting stuck at 7 plus or minus sqrt 309 / 26 13sin^2x-7sinx=5 solve for interval [0,360degrees]

they are squared and to the power of 4
