Question Taylor Polynomials
Engineers and physicists frequently use the approximation ~~ for small, which is a firstorder Taylor
polynomial approximation for centered at In this exercise we will use Taylor's theorem to create a
simple MATLAB function capable of telling us what degree of Taylor polynomial approximation is needed to obtain
a desired level of accuracy on a specified interval.
a Let be the degree Taylor Polynomial for about Find so that is within
of for all xin
b Create a MATLAB function that takes as input a positive parameter an interval radius call something
like delta in MATLAB and a desired error threshold err, and returns a value for which you can prove that
the order Taylor Polynomial for about is within err of for all xin Call
your function with suitable input values to reproduce your answer to question a
HINT: Your code does not need to be complicated! By mimicking your theoretical analysis from a you
should only "need" MATLAB at the very end of this problem, where you can write some code to find the first
satisfying a certain inequality, rather than looking for it by hand as we did in class
