Use the Trapezoidal Rule to approximate the area bounded by the graph of

between **x = 0** and **x = 3** and the **x**-axis. Use **N = 6**
trapezoids.

Using MPP:

- At the main menu, either enter 3
or use the arrow keys to move to
*3. Integral*and press - At the prompt,
*Interval of integration*, type in 0 for*a*and 3 for*b*. - At the prompt for function, type (cos(x))^3
- At the prompt,
*Method 1*type T - At the prompt,
*Number of intervals*, type 6 - Press to draw the graph.
- At this point, you will see the graph.
