Get started for freeHow may we find the Maclaurin series for f(x)g(x) if we already know the Maclaurin series for the functions f(x) and g(x)? How do you find the interval of convergence for the new series?
In Exercises 49–56 find the Taylor series for the specified function and the given value of . Note: These are the same functions and values as in Exercises 41–48.
What is a difference between a Maclaurin polynomial and the Maclaurin series for a function f ?
What is meant by the interval of convergence for a power series in ? How is the interval of convergence determined? If a power series in has a nontrivial interval of convergence, what types of intervals are possible.
Find the interval of convergence for each power series in Exercises 21–48. If the interval of convergence is finite, be sure to analyze the convergence at the endpoints.
