    Trapezoid Rule..

    Integral from 0 to 2 of x^2, n=4

    I don't get how to do this.. Do I graph the function and then make the subintervals??

    How can I solve this WITHOUT having to graph the function??

    first find change in x. so delta x = 2-0/4 or 1/2 then plug that into the trapezoidal rule formula so 1/4*(f(0) +2f(.5) + 2f(1) + 2f(1.5) + f(2))
    = (.5 + 2 + 4.5 + 4)/4 = 11/4.
