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
