The final problem in an assignment I have is making absolutely no sense, mainly because it sounds technical and I can't determine what's required of me.
The following is the problem:
So, first up, because of the theme of the assignment I'm assuming integration is involved with limits ranging from 0 to 0.01.A current:
amperes is applied across an electric circuit. Determine its mean and r.m.s values each correct to 4s.f., over the range t=0 to t=10 ms.
Integrating 45sin(100PI t) dt would result in (Correct me if I'm wrong, I believe chain rule is as in differentiation as integration, however it's in division instead of multiplication).
Finally, the main problem is, I need the mean and r.m.s, which I have no clue what it equates to from the values I find. Can someone please help clarify this problem?
EDIT: Just remembered, since this is what previous problems involved in the assignment, should I use the Trapezium/Mid-ordinate/Simpson's Rule instead by any chance, since Mean probably means average and r.m.s might have something to do with that?
Thanks and regards,
