If we cannot find an exact value for this number, it suffices to approximate it as long as our approximation is bigger than the actual number. I'm really struggling in this class and very confused. http://megavoid.net/error-bound/error-bounds-trapezoidal-rule-find-k.html

Another option for many of the "small" equation issues (mobile or otherwise) is to download the pdf versions of the pages. My approximations are correct, so I think I'm just misunderstanding how to find K. What I did: 2nd deriv f''(x)=-2x*sin(x2)-4x2cos(x2) since the graph is bounded by |1| I thought the max.

What Is An Error Bound Q.a) Find the approximations T8 and M8 for ∫(0 to 1) cos(x2)dx I found these to be T8=0.902333 and M8=0.905620 b) Estimate the errors in the approximations. Down towards the bottom of the Tools menu you should see the option "Compatibility View Settings". For sine or cosine, for example, you know the value is never larger than 1.

Trapezoid Rule For this rule we will do the same set up as for the Midpoint Rule.  We will break up the interval  into n subintervals of width, Then on In addition, using the maximum of $|f''(x)|$ usually gives a needlessly pessimistic error estimate.

Trapezoid Rule                    The Trapezoid Rule has an error of 4.19193129 Simpson’s Rule                    The Simpson’s Rule has an error of 0.90099869. So how big can the absolute value of the second derivative be?

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. Share this thread via Reddit, Google+, Twitter, or Facebook Have something to add? 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 $\le 2+\pi$.
