0 ¡Ü x ¡Ü 2(PI)

I have to find where the interval is increasing, decreasing, local mins and maxs, inflection points, and concave up and down. I understand how to do these type of problems. I am just getting messed up with the sin, cos, and pi stuff. So far I have

f'(x)= -12cos(x)sin(x)-12cos(x) and i have the critical numbers being -pi/2 and pi/2. and i am lost from there...
