Lower and Upper Sum
- Johanna Zöchbauer
- Integral Calculus
Use slider n in order to modify the number of rectangles used to calculate the lower and upper sum.
1. Compare the values of the upper sum / lower sum to the value of the integral for different values of slider n. What do you notice? 2. What happens to the difference of the upper and lower sum (a) if n is small (b) if n is big?
