( ) ( ) means the function is "odd"
Visually, it means that the left side of the graph is a mirror image of the
right side, but then flipped upside down.

To use the closed interval method, we need to find the values of the function
at the endpoints and also where the derivative of the function equals zero.
The largest y-value of these is the absolute maximum in the interval and the
lowest y-value is the absolute minimum in the interval.

The values of the endpoints are:
2
2sin 0.63
4 4 4 4 2
2sin 2 0.43
2 2 2 2
To get the derivative, we use the power rule and the derivative of
