Approximation Using Taylor POlynomial

Click For Summary
SUMMARY

The discussion focuses on approximating the value of e-0.1 using Taylor polynomials with an error margin of less than 10-3. Participants confirm that substituting -0.1 for x in the Taylor series expansion of ex is correct. The conversation emphasizes the need for a Taylor polynomial along with a remainder estimate to achieve the desired accuracy, rather than relying solely on the infinite series.

Find an approximate value of the number e-0.1 with an error less than 10-3

ı know that ex = Ʃ(from zero to ınfinity) xn / n!=1+x/1!+x

/2!+...

ı don't know how to use e-0.1 in this question.Do ı write -0.1 instead of x in ex series?

yup! :biggrin:
 
Since you are asked to calculate to within a particular accuracy, what you need is not the Taylor series, but a Taylor polynomial plus remainder estimate.
