    I have this question that I have worked out, but got a negative answer.
    The question is-

    Using the Composite Simpson’s Rule with n = 6 find an approximation to the integral
    f(x) = x^2cosx between pi and 0.

    I worked the following values-
    0, pi/6, pi/3, pi/2, 2pi/3, 5pi/6, pi
    and their answers from f(x).

    and completed the Simpsons rule.

    final answer i got is -6.274868358/88.

    Is it right??

    From software, I get -6.2832, so your working is probably correct.
