 Work through the following steps to evaluate (212 + 5) do.

Work through the following steps to evaluate (212 + 5) do. a) We know that a = and b = b) Using n subintervals, Ax = c) Assume that the sample points in each interval are right endpoints. Find the following sample points: C1 = 2 2 C 3 In general, the ith sample point is ci = Note: your answer will be an expression in terms of i and n. d) Now find the sum of the areas of n approximationg rectangles. Note: your answer will be an expression in terms of n. i = 1 e) Finally, find the exact value of the integral by letting the number of rectangles approach infinity. (22 + 5) da = lim 1 + 00
