6.2.3
![**Problem Statement**
Given:
\[ C(x) = \sum_{n=0}^{\infty} \frac{(2n)!}{(2n)^{2n}} x^{2n} \]
and
\[ S(x) = \sum_{n=0}^{\infty} \frac{(2n+1)!}{(2n+1)^{2n+1}} x^{2n+1} \]
Find the power series of \( C(x) + S(x) \).
**Solution**
The problem requires the sum of the two power series \( C(x) \) and \( S(x) \) and finding a combined power series representation.
\[
\sum_{n=0}^{\infty}
\]
Consider combining terms of both series and analyze the patterns in the coefficients.
**Notes**
- The factorial terms \((2n)!\) and \((2n+1)!\) in the numerators indicate the growth of each term.
- The denominators \((2n)^{2n}\) and \((2n+1)^{2n+1}\) account for normalization.
- The powers of \(x\) are even for \(C(x)\) and odd for \(S(x)\), suggesting interleaving.
