(a) Find the approximations T10 and M10 for 2 21e1/x dx. 1 (Round your answers to six decimal places.) T10 = 46.461489 M10 = 42.401140 (b) Estimate the errors in the approximations of part (a). (Round your answers to six decimal places.) |ET| ≤ |EM| ≤ (c) How large do we have to choose n so that the approximations Tn and Mn to the integral in part (a) are accurate to within 0.0001? n = for Tn n = for Mn
