Question

Use the Geometric Series Test to help you find a power series representation of f(x) = x/(2 + x^3)
centered at 0. Find the interval and radius of convergence.

Expert Solution
Given a function

f(x)=x2+x3

To Find: power of series

Note:

The geometric power series is a series of the form a1-r=n=0arn, r<1Where a is the first term and r is the common ratio.

This implies f(x)=x2+x3                            =x2·11+x32
