Determine constants a,b,c,d,e that will produce a quadrature formula:the integral from -1 to 1 of f(x)dx = af(-1) + bf(0) + cf(1) + df'(-1) + ef'(1)that has degree of precision 4.I thought that I could set up a system of equations by taking the integrals from 0 to 1 of 1, x, x^2, x^3, and x^4 and setting them equal to the various combinationsof those constants but I don't know how to configure the constants.
