In this activity, students calculate Riemann sums. They demonstrate when the Riemann sums will over-approximate a definite integral. They also observe the convergence of Riemann sums as the number of subintervals get larger.
Students will calculate and analyze Reimann sums.
Students will use a calculator program to automate the process of calculating the sum.
Students will observe the convergence of left-hand and right-hand Riemann sums by using graphing
handhelds to automate the production of Riemann sums with regular partitions having a large number of subintervals.
