Problem 21RE

Power series from the geometric series Use the geometric series $$\sum_{k=0}^{\infty} x^{k}=\frac{1}{1-x}$$, for |x| < 1 to determine the Maclaurin series and the interval of convergence for the following functions.

$$f(x)=\frac{1}{1-x^{2}}$$

Step-by-Step Solution:

Solution 21RE

Step 1:

In this problem we have to use the geometric series for |x|<1, to determine the Maclaurin series of and also we have to find the interval of convergence.

We have

Using geometric series  for |x| < 1 we get,

Thus the Maclaurin series of is given by

Notice that we replaced both the x in the geometric series with to get the required Maclaurin series and so we will do the same in the interval of convergence.

Thus  provided

Thus the interval of convergence for the Maclaurin series is . That is  the interval of convergence is
