Learning Objectives 3a and 3c Rubric: "1" correctly set up the limit of a Riemann sum and evaluate the limit of the Riemann sum for 3a, and correctly use FTC II to evaluate the integral for 3c. "0" incomplete work or incorrect answers. The goal in this problem is to rewrite the following definite integral as a limit of a Riemann sum. Your final expression should not have Ax or X; in it; these must be more specific and should be in terms of an indexing variable. [ x dx. Learning Objective 3a (Part a.-c.) a. Find the following: Ax = X; = b. Rewrite the integral as a limit of a Riemann sum. c. Evaluate the integral by evaluating the limit in part b. Learning Objective 3c (Part d.) d. Check your work by evaluating the integral using the Fundamental Theorem of Calculus
