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). We can do better than that by looking at the second derivative in more detail, say between $0$ and $\pi/4$, and between $\pi/4$ and $\pi/2$. Why is the background bigger and blurrier in one of these images? Please do not email asking for the solutions/answers as you won't get them from me.

Another option for many of the "small" equation issues (mobile or otherwise) is to download the pdf versions of the pages. Here's why. You should see an icon that looks like a piece of paper torn in half.

Show Answer Short Answer : No. I also have quite a few duties in my department that keep me quite busy at times. Those are intended for use by instructors to assign for homework problems if they want to. I used $|E_{T}| <= \frac{K(b-a)^3}{12n^2}$ On the process of this formula, I did take 3rd derivative of given function which was $x\cos x$ to find out max of 2nd derivative.

It is especially true for some exponents and occasionally a "double prime" 2nd derivative notation will look like a "single prime". Loading...

In the interval from $0$ to $\pi/2$, our second derivative is less than $2+\pi/2$. We can do this and analytically and determine the maximum is 2. Once you have made a selection from this second menu up to four links (depending on whether or not practice and assignment problems are available for that page) will show up this contact form The first goal is to find the maximum of | f''(x) | on [1,2].

Most of the classes have practice problems with solutions available on the practice problems pages. Some of the equations are too small for me to see! Select this option to open a dialog box.

The usual procedure is to calculate say $T_2$, $T_4$, $T_8$, and so on until successive answers change by less than one's error tolerance. So, from these graphs it’s clear that the largest value of both of these are at . So, We rounded to make the computations simpler. The area of the trapezoid in the interval is given by, So, if we use n subintervals the integral is approximately, Upon doing a little simplification It's not worth it.

Can 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 You will be presented with a variety of links for pdf files associated with the page you are on. The number $x$ could be as large as $\pi$.In the mean time you can sometimes get the pages to show larger versions of the equations if you flip your phone into landscape mode. Links - Links to various sites that I've run across over the years. Are MySQL's database files encrypted? So I just stack there.

Thus, if we use $K=2+\pi$, we can be sure that we are taking a pessimistically large value for $K$. Let's be very pessimistic. So we have reduced our upper bound on the absolute value of the second derivative to $2+\pi/2$, say about $3.6$.

The question says How large should $n$ be to guarantee the Trapezoidal Rule approximation for $\int_{0}^{\pi}x\cos x\,dx$ be accurate to within 0.0001 ? Sign in to make your opinion count.
