Let I = S, a2 dac. Find the errors EL, ER, EM, ET for L3, R1, M1, T3, respectively. EL = ER = ET = EM = Determine n so that the approximations are accurate within 0.1 by finding the maximum values of the absolute values of the first and second derivatives of the integrand, a2, on the interval [1, 4]. n for In is n for Run is n for In is n for Mn is
