Question

What is the 2nd order Taylor series estimated value of the sqrt(40)? Use sqrt(36) = 6 as your known starting point. what is the estimated error of your answer?

Answer #1

What is the 2nd order Taylor polynomial of the function f (x) =
sqrt(x) at point a = 4? Please solve it!!!

Use Taylor Series to estimate the value of ln(3.4) knowing
that the value of ln(1)=0 ,Perform the calculations until the 4th
order term of the series. At each step of your calculation, find
the relative approximate error.

Use a 2nd order Taylor polynomial centered at x = 4 to
approximate √4.001 You can leave your answer as the sum or
difference of fractions.

Use zero to third order approximations, respectively to
determine f(x) = (4x - 6)3
using base point xi = 2 by Taylor series
expansion. Approximate f(4) and compute true percent
relative error |εt| for each approximation.
