Would you mind if you explain more ? –Ryu Feb 28 '12 at 5:47 @Ryu: André Nicolas has done a very good job, so I will refer you to Simpson’s Rule This is the final method we’re going to take a look at and in this case we will again divide up the interval  into n subintervals.  However unlike the Check This Out

We get $$f''(x)=-x\cos x-\sin x-\sin x=-(2\sin x+x\cos x).$$ Now in principle, to find the best value of $K$, we should find the maximum of the absolute value of the second derivative.

Error Approx. Uploaded on Dec 12, 2010Calculus: The Trapezoid Rule is used to approximate the area under the curve f(x) = (1+x)^2 over the interval [0,2]. Solution We already know that , , and  so we just need to compute K (the largest value of the second derivative) and M (the largest value of the fourth derivative).  http://u2commerce.com/trapezoidal-rule/trapezoidal-rule-error.html None of the estimations in the previous example are all that good.  The best approximation in this case is from the Simpson’s Rule and yet it still had an error of

For "nice" functions, the error bound you were given is unduly pessimistic. So, because I can't help everyone who contacts me for help I don't answer any of the emails asking for help. Loading... Let me know what page you are on and just what you feel the typo/mistake is.

The absolute value of $\cos x$ and $\sin x$ is never bigger than $1$, so for sure the absolute value of the second derivative is $\le 2+\pi$. However, I got some strange number. So let $f(x)=x\cos x$. Watch QueueQueueWatch QueueQueue Remove allDisconnect Loading...
