Homework Help: Write down the linear of system of equations

  1. Apr 10, 2010 #1
    1. The problem statement, all variables and given/known data

    write down the linear system of equations that must be satisfied to find the Newton-Cotes quadratic rule for the interval [0,1] that is exact for polynomials of degree 3 and uses the sample points x1=0, x2=1/3, x3=2/3, and x4= 1


    2. Relevant equations

    none



    3. The attempt at a solution

    I know hot to do find the equations for the cubic polynomial in the standard bases given a equation, but I don't how to do it this way. Is not homework is a sample test, for the test that I have on monday.

    Thanks
