## Homework Statement

Find the error bound using Simpsons Rule for integral of SQRT (x) dx from 1 to 9.[/B]

## Homework Equations

E = (M * (b-a)^5) / (180 * n^4), where M = max value of the 4th deriv of x dx

[/B]

## The Attempt at a Solution

see attached please - I can't figure out what to use for the value of M, which is supposed to be the maximum value of the 4th derivative. I graphed the 4th deriv (see attached) and the max y = 0 and the max x is infinity? I need help figuring out M please thanks.https://www.dropbox.com/s/3cn5q3n96iutgu4/IMG_6352.JPG?dl=0 [/B]
