    The sketch shows the finite region bounded by
    the curve and the x-axis,

    This region is rotated 2π radians about the x-axis,
    Find the exact value of volume of the generated.
    i got

    π∫(xsin^½x)² dx
    π∫(x²sinx) dx

    now im gonna use integration by parts on that twice if neccessary and sub in the limits, is that the right way and btw i may sound like a noob, but is the algebra correct above when expanded brackets.
