Suppose we have the series of functions:
\begin{equation} F(x)=\sum_{n=1}^{\infty} f_n(x) \end{equation}
where convergence is uniform.
Additionally, consider the partial functions of the series:
\begin{equation} F_m (x)=\sum_{n=1}^{m} f_n(x) \end{equation}
Suppose that:
\begin{equation} \int_{0}^{1} \frac{F_m(x)}{x^{3}} ,dx \end{equation}
forms a Cauchy sequence, hence convergent.
Can we then claim that:
\begin{equation} \int_{0}^{1} \frac{F_m(x)}{x^{3}} ,dx \to \int_{0}^{1} \frac{F(x)}{x^{3}} ,dx \end{equation}
as $m \to \infty$?
Obsobservation: \begin{equation} \int_{0}^{1} \frac{F(x)}{x^{3}} ,dx \end{equation}
