with N rectangles where N = 10 and 50.

1. Choose Beginning Calculus from the initial menu and press .
2. Use the arrow keys to move to the menu item Riemann Sums, press and .
3. At the prompt F(x) =, enter the formula x^2+1
4. Enter the bounds at the prompts

   x_0 = 0

   x_1 = 2

5. Using the arrow keys, move to F(Midpoint) and press
6. (*) At the prompt for the number of subdivisions, N = , enter 10
7. You will see the the graph of the function and the approximating rectangles:

   

8. Hitting , you will see the calculations up to that point.
9. Hit , again and use the arrow keys to move to Change N Only and press .
10. Return to (*) and enter N = 50 and proceed as above.

    

    You will see the following table at some point:
