  1. Apr 19, 2010 #1
    1. The problem statement, all variables and given/known data

    Assume that sin(x) equals its Maclaurin series for all x.
    Use the Maclaurin series for sin(3 x^2) to evaluate the integral
    int_0^{0.72} sin(3 x^2) dx.
    Your answer will be an infinite series. Use the first two terms to estimate its value.

    2. Relevant equations
