4. (continued) b(i). Evaluate the following definite integral. (Your answer should be in terms of a and b.) 2 1/2 dx = b(ii). Use your previous answer to evaluate the limits. lim x 1/2dx = lim x 1/2dx = a-+0+ b(iii). Using your previous answer, write down "CONVERGES" if the integral converges, and "DIVERGES" if it diverges. If the integral converges, write down the number to which it converges. x-1/2 dx
