Use the Midpoint Rule to approximate

with *N* rectangles where *N = 10* and *50*.

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 2 for*b*. - At the prompt for function, type x^2+1
- At the prompt,
*Method 1*type M - At the prompt,
*Number of intervals*, type 10 - Press to draw the graph.
- At this point, you will see the graph.
- Press
and, at the prompt,
*Method 2*type M again. - At the prompt,
*Number of intervals*, type 50 - Press to draw the graph.
