Extracted text: Find the approximations L, R, Tn, and M, 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.) Ln Rn M. 5 10 20 E 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, E, and Eg are decreased by a factor of about and Er and EM are decreased by a factor of about
