    How far have you gotten so far? Have you calculated your interval?

    ΔX = (b - a)/n

    Ages since I've used it. However...go to Google and search Simpsons rule sample and there are loads of presolved equations for you. It generally just becomes a case of substitution...

    Above link should sort you out OP. It's been years since I've used Simpson's rule but this served as a good reminder.

    Speak to your teacher to get up to speed. You need to learn it properly.

    i^2 = sin^2

    /int sin(t)^2 dt = t/2 - sin(2t)/4

    =>

    /int_0^2pi sin(t)^2 dt = pi

    So plug it all in and RMS = 1/sqrt(2)
