The complication here is delta x is different on different intervals:
(0, pi/6, pi/4, pi/3, pi/2)
dx1 = dx4 = pi/6
dx2 =dx3 = pi/12
I need some help with this problem.
It goes like this..
Approximate the integral of sin(x) dx from the 0 to pi/2 by computing the left-hand and right-hand sum. Use the partitions (0, pi/6, pi/4, pi/3, pi/2)
I guess I'm just having troubles finding delta x.
The first attempt I tried was using b-a/n which i did pi/2 - 0 /4 which give me pi/8 but that was an incorrect answer. I kinda guessed it because b-a/n wouldn't work because they dont go up by the same intervals.
I think that if I can find delta x then it would be easy sailing from tehre
Never underestimate the power of a clear diagram. Once you understand what you're doing and all this becomes clear and obvious, you may not need them - but they're *always* useful for communication. (Obviously not easy to reproduce on a computer, it's more for your own personal benefit.)
