In general, the further away is from , the bigger the error will be. Discussion. Error defined Given a convergent series Recall that the partial sum is the sum of the terms up to and including , i.e., Then the error is the difference between and The links for the page you are on will be highlighted so you can easily find them. https://www.khanacademy.org/math/ap-calculus-bc/series-bc/estimating-infinite-series-bc/v/alternating-series-error-estimation

Alternating Series Error Bound

Loading... Example 3  Using  to estimate the value of . Solution The series converges by the Alternating Series Test because and The sum of the first six terms is and, by the Alternating Series Remainder, you have So, the sum S

There is a slightly different form which gives a bound on the error: Taylor error bound where is the maximum value of over all between 0 and , inclusive. Alternating Series Error Approximation You should see an icon that looks like a piece of paper torn in half.

Then |rn|http://archives.math.utk.edu/visual.calculus/6/series.10/ 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,                                              

But remember, we want the guarantee of the integral test, which only ensures that , despite the fact that in reality, . Error Estimation Where are the answers/solutions to the Assignment Problems? To fix this problem you will need to put your browser in "Compatibly Mode" (see instructions below). Again, we can see that the remainder, Rn, is again this estimation and in this case it will underestimate the area.  This leads to the following inequality, (3) Combining

Alternating Series Error Bound First, we’ll start with the fact that Now, if we use (2) we get, Likewise if we use (3) we get, Putting these Alternating Series Error Calculator One way to get an approximation is to add up some number of terms and then stop.

Alternating Series Error Proof

Example Consider the case when . Before we get into how to estimate the value of a series let’s remind ourselves how series convergence works.  It doesn’t make any sense to talk about the value of a Published on Jul 1, 2011Alternating Series - Error Estimation. this content Note If you actually compute the partial sums using a calculator, you will find that 7 terms actually suffice.

In this case we’ve used the ratio test to show that  is convergent.  To do this we computed and found that . Error Of Alternating Series Test The goal is to find so that .

What we want to do is determine how good of a job the partial sum, will do in estimating the actual value of the series .  Again, we will But how many terms are enough?
