Find the approximations Tn, Mn, and 5,, to the integral / 1 4 11 \\/; dx for n = 6 and 12. Then compute the corresponding errors ET, EM, and E5. (Round your answers to six decimal places. You may wish to use the sum command on a computer algebra system.) n 6 Tn Mn 5n 12 What observations can you make? In particular, what happens to the errors when n is doubled? As n is doubled, ET and EM are decreased by a factor of about , and E5 is decreased by a factor of about
