4. (7.2 7a) An alternative way to derive the Quadrature rules without Lagrange Interpolating Polynomials is to use the Method of Undetermined Coefficients. In particular, we can derive Simpson's rule by solving the following problem: Find the constants wo, w1, W2 so that g(t)dt = wog(0) +w19(1/2) + w29(1) so that the approximation is exact for g(t) = 1, g(t) = t, g(t) = t.
