Alternating series error bound For a decreasing, alternating series, it is easy to get a bound on the error : In other words, the error is bounded by the next term Select this option to open a dialog box.

However, even if we prove that a given series converges, we so far did not advance in the problem of knowing how close is the zillion-long summation to infinite summation.

So This bound is nice because it gives an upper bound and a lower bound for the error.

What can I do to fix this? Alternating Series Error Proof First, we do not really need all terms of the series to be positive, since to get an upper estimate we may pass to absolute value. The equations overlap the text! patrickJMT 94,283 views 7:46 Absolute Convergence, Conditional Convergence and Divergence - Duration: 11:21.

Alternating Series Approximation Theorem

For examples see Methods Survey - Summing up series and Solved Problems - Summing up series, namely this problem and this problem. In the last two examples we’ve seen that the upper bound computations on the error can sometimes be quite close to the actual error and at other times they can be Alternating Series Approximation Calculator The links for the page you are on will be highlighted so you can easily find them. Approximating The Sum Of An Alternating Series This brings us to our first observation.

In this example, I find the number of terms required so that we can estimate the value of our convergent alternating series correct to two decimal places. http://bsnux.com/alternating-series/alternating-series-error-bounds.html This means solving the inequality RN

I've found a typo in the material. How To Do Alternating Series Test Now, let’s compute the integrals.  These are fairly simple integrals so we’ll leave it to you to verify the values.                                      Plugging these into (4) gives us,                                        Note for Internet Explorer Users If you are using Internet Explorer in all likelihood after clicking on a link to initiate a download a gold bar will appear at the bottom

Only if we prove that a series converges it starts making sense to do some numerical calculations.

From the proof of the Alternating Series Test we can see that s will lie between  and  for any n and so, Therefore,                                                                         We needed My Students - This is for students who are actually taking a class from me at Lamar University. Suppose that the series converges to L; let rn=L-sn where sn denotes the nth partial sum. Use The Alternating Series Estimation Theorem To Determine How Many Terms patrickJMT 317,178 views 11:21 Alternating Series - Error Estimation #2 - Duration: 1:16.

Note that here we asked how large the error RN is when we sum up to N, but often the question goes the other way around. Sign in to report inappropriate content.

Comparison Test In this case, unlike with the integral test, we may or may not be able to get an idea of how good a particular partial sum will be as I really got tired of dealing with those kinds of people and that was one of the reasons (along with simply getting busier here at Lamar) that made me decide to Thus, Thus, < Taylor series redux | Home Page | Calculus > Search Page last modified on August 22, 2013, at 01:00 PM Enlighten theme originally by styleshout, adapted by David Watch Queue Queue __count__/__total__ Find out whyClose Alternating Series - Error Estimation patrickJMT SubscribeSubscribedUnsubscribe586,086586K Loading...

To see why the alternating bound holds, note that each successive term in the series overshoots the true value of the series. Solution First, let’s use the ratio test to verify that this is a convergent series.                                             So, it is convergent.  Now let’s get the estimate.                                                     To determine an The obvious idea is to try to approximate it by summing up not all (that is, infinitely many) terms, but only the first few (thousand, million,...). Solution This is an alternating series and it does converge.  In this case the exact value is known and so for comparison purposes,                                              Now, the estimation is,
