Finding the area under the curve of a function. This presentation shows how Upper and Lower limits get closer to each other, as you increase n ( the number of increment of x), and to the Real Value of the Integral under the Curve.

1. Set the slider to n = 10, Record the values for Upper and Lower limits and Find the difference between those values.
2. Set the slider to n = 70, Record the values for Upper an Lower limits and find the difference between those values.
3. Explain in your own words why those limits are not equal and Why they are not equal to the Real Integral under the Curve...
