3. (a) Determine value for the coefficients A0, A₁, and A2 so that the quadrature formula I (ƒ) = [" | f (x) dx = Aof ( − ³½³) + A₁f (³½³) + 1 has degree precision at least 2. + A2f (1). (b) Once the values of A0, A1, and A2 have been computed, determine the overall degree of precision for the quadrature rule.
