Can Absolute Error Be Negative
2010 Notes on Taylor Polynomial Error Bounds – October 20, 2010 We'll mean absolute error start by discussing the formal error bound for Taylor polynomials. (I.e., how badly does a Taylor polynomial approximate absolute percent error a function?) Then, we'll see some standard examples. Finally, we'll see a powerful application of the error bound formula. Lagrange Error Bound for We know that the th Taylor https://www.youtube.com/watch?v=G2VTdqGODjM polynomial is , and we have spent a lot of time in this chapter calculating Taylor polynomials and Taylor Series. The question is, for a specific value of , how badly does a Taylor polynomial represent its function? We define the error of the th Taylor polynomial to be That is, error is the actual value minus the Taylor polynomial's http://math.jasonbhill.com/courses/fall-2010-math-2300-005/lectures/taylor-polynomial-error-bounds value. Of course, this could be positive or negative. So, we force it to be positive by taking an absolute value. The following theorem tells us how to bound this error. That is, it tells us how closely the Taylor polynomial approximates the function. Essentially, the difference between the Taylor polynomial and the original function is at most . At first, this formula may seem confusing. I'll give the formula, then explain it formally, then do some examples. You may want to simply skip to the examples. Theorem 10.1 Lagrange Error Bound Let be a function such that it and all of its derivatives are continuous. If is the th Taylor polynomial for centered at , then the error is bounded by where is some value satisfying on the interval between and . Explanation We derived this in class. The derivation is located in the textbook just prior to Theorem 10.1. The main idea is this: You did linear approximations in first semester calculus. What you did was you created a linear function (a line) approximating a funct

It's been a while since I've taken the Calculus and I'm afraid I need some refreshing, even for this textbook problem. Here is my approach, but I am almost certain something is amiss: Taylor's Theorem states that the $n$th remainder polynomial for the nth Taylor polynomial is $$R_n(x)= \frac{f^{(n+1)}(c) \ (x-a)^{n+1} }{(n+1)!} ,$$ where $a$ is the center and the existence of $c \in [a,x]$ is guaranteed by the Mean Value Theorem. I found the $4^{th}$ derivative of $\ln (1+x)$ to be $-\frac{6}{(x+1)^4}.$ The absolute error is given by $M\frac{|x-a|^{n+1}}{(n+1)!}$, where $|f^{(n+1)}(x)|≤M, x\in[0, .09]$. Since the $4^{th}$ derivative is just a hyperbola shifted to the left $1$ unit and "scaled" by a factor of $-6$, the graph has two branches with no inflection points, therefore only the endpoints of the interval $[0,.09]$ need be checked. The value of $0$ gives the greatest magnitude, and so $$ |R_3(x)|= 6\frac{x^{3+1}}{(3+1)!}=\frac{x^4}{4} .$$ Evaluating this at $x=.09$ (because the original function was $\ln(x+1)$ and I am trying to
