How do I find error bounds for approximate integrals? (image included).
More specifically, how do I get "K"? :/
where is example 1?
one moment!
Here it is. Example 1
\[K\ge|f''(x)|\]
So I keep differentiating until I get a constant?
I don't really understand.
you have an interval from a to b|dw:1334378877377:dw|
x rests between this interval right?
Correct.
\[a\le x\le b\] \[\frac{a\le x\le b}{x}\] \[\frac{a}{x}\le 1\le \frac{b}{x}\]
So, this is equal to K? What is K supposed to be?
As in, what does it represent?
Im not sure what it represent at the moment, im just trying to follow the information
do we have a different problem with an answer thats chkable so that we can play with it?
Simpson Rule, but i think this may do.
And this is the error bound formula for Simpson rule
i think the K is a maximum for f'' .... but i cnt be sure yet
Suppose that the second derivative f'' is continuous on [a, b] and suppose that |f''(x)| <= M for all x in [a, b]. Reads to me like M is a max
or K in this case

Ah ha! That link helped. M does appear to be a max.
