7. Solve each equation for solutions on the interval [0,2-). Find all exact solutions where appropriate. Round approximate answers in radians to two decimal places. In other words if you can find an exact solutions (ie found on the unit circle) write it in exact form. If it's not possible ſie. not on the unit circle) then round to two decimal places. a) 3 cos 0-cos02 b) cos2x-sinx=0 c) cos3x
