Math 252 Week 3 Activity - Fall 2023 Page 5 of 5 (5) Compute a right Riemann, R4, sum for 4x2 - 13 on [-2, 3]. (6) Consider the definite integral Fill in all the entries of the sigma notation needed to represent the definite integral as a right Riemann sum in terms of constants and n, where n represents the number of subintervals. Note: The only variable(s) in your summation should be n and the index of your summation. That is, there should be no r variables in your summation. 7) Joe gets a new pair of running shoes.
