Best ResponseYou've already chosen the best response.0Use the derivative:\[f'(x)=12\cos x\]Solve the equation:\[f'(x)=0 \Leftrightarrow 12\cos x = 0 \Leftrightarrow \cos x = \frac{ 1 }{ 2 }\]There are two solutions in [0, 2pi]. These are the xvalues where f has a (local) extreme. You can calculate the extremes by substituting the solutions of f' in f. Also calculate f(0) and f(2pi) to get the extremes in the endpoints. If you have all the extremes, you can decide what the absolute maximum and minimum values are.
