(1 point) (a) Evaluate the integral Your answer should be in the form kT, where k is an integer. What is the value of k? (Hint: darctan(z)- dr 2+1 tb) Now, lets evaluate the same integral using power series. First, find the power series for the function f(). Then, integrate it from 0 to 2, and call it S. S should be an infinite series an What are the first few terms of S 16 2+4...
