### Fourier Series Application

#### Example:
Using the Fourier Series for \( f(x) = |x| \) in the interval \(-\pi < x < \pi\),

#### Task:
Find the sum of the series \( \frac{1}{1^2} + \frac{1}{3^2} + \frac{1}{5^2} + \cdots \) assuming that the Fourier series of the function \( f \) at \( x = 0 \) converges to \( f(0) \).

#### Further Analysis:
Using Parseval's identity to calculate ...
