Okay, it’s time to work an example and see how these rules work. Usually then, $f''$ will be more unpleasant still, and finding the maximum of its absolute value could be very difficult. share|cite|improve this answer edited Feb 28 '12 at 7:41 answered Feb 28 '12 at 6:13 André Nicolas 418k31358699 add a comment| up vote 0 down vote Hint: You don't say what numericalmethodsguy 55 171 visningar 7:19 ch4 3: Error estimate for trapezoid rule. have a peek here

Midpoint Rule This is the rule that should be somewhat familiar to you.  We will divide the interval  into n subintervals of equal width, We will denote each of Furthermore, assume that f''(x) is continous on [a,b]. Having solutions (and for many instructors even just having the answers) readily available would defeat the purpose of the problems.
