1. we are interested in approximatingin(x1) dr. (a) (6 points) if we use simpson's rule, how many intervals must we use in order to be certain that our approximation of is accurate within 10- -12 (b) (6 points) if we use adaptive quadrature with 10, do we accept the s(2,3)s(3,4) approximation? to get you started, s(2,4) 2.7511 and s(2,3 1.2493. acce
