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...

I havent.

I missed all the classes when this was discussed, due to illness.

As Dis86 said, it's pretty much a case of substitution. Long winded but pretty simple - first YouTube result:

See how far you get with that.

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)
