QUESTION:
Series to functions Find the function represented by the following series and find the interval of convergence of the series.
\(\sum_{k=0}^{\infty}\left(x^{2}+1\right)^{2 k}\)
ANSWER:Solution 52EStep 1:In this problem we have to find the function represented by the series and also we have to find the interval of convergence of the series . = 1+ +++................ Is an infinite geometric series and use the formula for a geometric series. That is , with |r| > 1Therefore , = , for || > 1 ( Since = , for | > 1) = , since +2ab+ = for || > 1 = for || > 1Thus the function represented by the power series is =
