SUMMARY

The discussion focuses on estimating the range of values for x in the Taylor polynomial approximation of sin(x) = x - (x^3)/6, ensuring the error remains below 0.01. Participants suggest using the Alternating Series Estimation Theorem or Taylor's Inequality to determine the truncation error. The consensus indicates that understanding the Alternating Series Estimate is crucial for accurately estimating the error in this context. The user is encouraged to research these concepts to proceed effectively with their homework.

PREREQUISITES
  • Understanding of Taylor series and their applications
  • Familiarity with the Alternating Series Estimation Theorem
  • Knowledge of Taylor's Inequality
  • Basic calculus concepts, particularly series convergence
NEXT STEPS
  • Research the Alternating Series Estimation Theorem in detail
  • Study Taylor's Inequality and its applications in error estimation
  • Practice deriving Taylor series for various functions
  • Explore examples of error estimation in polynomial approximations
USEFUL FOR

Students studying calculus, particularly those working on Taylor series and error estimation, as well as educators looking for teaching resources on these topics.

Homework Statement



I can either use the alternating series estimation thereom (which i don't really know) or Taylor's Inequality to estimate the range of values of x for which the given approximation is accurate to within the stated error.

sin(x) = x - (x^3)/6 (|error| < 0.01)

Do I just start writing out the terms of the sine series? I'm not sure exactly what I'm supposed to do here.

You are supposed to estimate the error in a truncation of the infinite series. As you don't seem to know either the alternating series estimate or the Taylor series remainder term, I think you will need to look at least one of them up. Can you do that? I would suggest starting with the alternating series version. It's easier.
 
thanks, Dick, I will look that up
