geometric series error estimate Wolfeboro, New Hampshire

First, let’s remind ourselves on how the comparison test actually works.  Given a series  let’s assume that we’ve used the comparison test to show that it’s convergent.  Therefore, we found a Embed Size (px) Start on Show related SlideShares at end WordPress Shortcode Link 03 truncation errors 18,659 views Share Like Download maheej Follow 0 0 0 Published on Jan 4, 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 Professor Leonard 48,984 views 1:19:45 Alternating series estimation theorem - Duration: 13:12.

Observation• A Taylor series converges rapidly near the point of expansion and slowly (or not at all) at more remote points. 22 23. That is the purpose of the last error estimate for this module. Sometimes, we need to find the critical points and find the one that is a maximum. Links to the download page can be found in the Download Menu, the Misc Links Menu and at the bottom of each page.

That is 1 1 ≥ ∀ ≥1 j j 3 1+ j3 ∞ 1 1 So Rn ≤ ∫ 3 dx = n x 2n 2 31 32. Note that if you are on a specific page and want to download the pdf file for that page you can access a download link directly from "Downloads" menu item to Also most classes have assignment problems for instructors to assign for homework (answers/solutions to the assignment problems are not given or available on the site). That's going to be 144, and then that's going to be 144 minus 36/144, plus 16/144, minus 9/144.

Secondly, is there any way to make the estimate better?  Sometimes we can use this as a starting point and make the estimation better.  We won’t always be able to do Khan Academy 52,701 views 9:18 113 videos Play all PatrickJMT's Sequences and Series in Orderritoruchou Lagrange Error Bound - Duration: 4:56.

Infinite series. Now, this was one example. Class Notes Each class has notes available. Let's write the remainder down.

Dr Chris Tisdell - What is a Taylor polynomial? Same problem with larger step sizeWith x = 0.5, 0 ≤ c ≤ 0.5, f ( x ) = e x => f ( n +1) ( x ) = e Before moving on to the final part of this section let’s again note that we will only be able to determine how good the estimate is using the comparison test if The Remainder of the Taylor Series Expansion f ( n +1) ( c) n +1 n +1 Rn = h = O (h ) ( n + 1)!SummaryTo reduce truncation errors,

Solving for gives for some if and if , which is precisely the statement of the Mean value theorem. tj 6 < 0.11If you can find this k, then k = 0.11, t6 < 3 ×10 −6 k tn Rn ≤ k tn 0.11 1− k R6 ≤ < ×3 In other words, is . Sign in 7 Loading...

If you see something that is incorrect, contact us right away so that we can correct it. Show Answer Yes. tj jπ−2 j j|tj+1| ≤ k|tj| or |tj+1|/|tj| ≤ k t j +1 1 ≤ 1 + π−2 ∀ ≥6 jfor all j ≤ n (n=6)? However, since we know that \(z\) is between \(a\) and \(x\), we can determine an upper bound on the remainder and be confident that the remainder will never exceed this upper

The first thing I want to see is, I want to show you that this remainder right over here is definitely going to be positive. for some c between a and xFor f(x) = ex and a = 0, we have f(n+1)(x) = ex. Then |rn|

So, let’s start with the series  (the starting point is not important, but we need a starting point to do the work) and let’s suppose that the series converges to s.  and it is, except for one important item.

It's going to be different depending on whether the first term is negative or positive, and we're going to have to introduce the idea of absolute value there, the magnitude.

Part 3Truncation Errors 1 2. See why. What sense of "hack" is involved in "five hacks for using coffee filters"? But remember, we want the guarantee of the integral test, which only ensures that , despite the fact that in reality, .

Let's see, that is 144, negative 36 plus 16 is minus 20, so it's 124 minus nine, is 115. Exact mathematical formulation 12 13. patrickJMT 241,439 views 12:47 Alternating Series - Duration: 6:01. n! ( n + 1)!• How to derive the series for a given function?• How many terms should we add?

R four is going to be greater than zero.

I'm assuming you've had a go at it. The function is , and the approximating polynomial used here is Then according to the above bound, where is the maximum of for .

If , then , and so by the alternating series error bound, . So, what is the value of \(z\)? \(z\) takes on a value between \(a\) and \(x\), but, and here's the key, we don't know exactly what that value is. Exercise π4 1 1 1 =1 + 4 + 4 + 4 +... 90 2 3 4How many terms should be taken in order to computeπ4/90 with an error of at Or, we could even write that as R sub four is less than 0.04. 0.04, same things as 1/25.

The point is that once we have calculated an upper bound on the error, we know that at all points in the interval of convergence, the truncated Taylor series will always

Notice that in the numerator, we evaluate the \(n+1\) derivative at \(z\) instead of \(a\).
