Find the approximations Ln, Rn, Tn, and My to the integral 37xex dx for n = 5, 10, and 20. Then compute the corresponding errors EL, ER, ET, and EM. (Round your answers to six decimal places. You may wish to use the sum command on a computer algebra system.) n Ln Rn In 5 25.488886 47.604172 37.546529 36.726977 10 20 n EL ER ET EM 5 10 20 What observations can you make? In particular, what happens to the errors when n is doubled? As n is doubled, EL and ER are decreased by a factor of about , and ET and EM are decreased by a factor of about
