| 0% | I.
For the function $$f(x)=\cos(x)$$ on the interval $$[-\frac{\pi}{2}, \frac{\pi}{2}]$$, the average value is computed as $$\frac{1}{\pi} \int_{-\frac{\pi}{2}}^{\frac{\pi}{2}} \cos(x)\,dx = \frac{2}{\pi}$$.
II.
By symmetry, one might incorrectly assume that the average equals $$\cos(0)=1$$, but this is not the case.
III.
Using the integral method confirms that the correct average value is indeed $$\frac{2}{\pi}$$.
