This equation was written with the following code:

LaTeX:

```
\begin{widetext}
\begin{equation}
f(x) = \frac{1}{4} + \frac{2}{\pi}\left(-\frac{\cos{x}}{2} + \frac{\cos{3x}}{6} - \frac{\cos{5x}}{10} + \cdots \right) + \frac{2}{\pi}\left(\frac{\sin{x}}{2} - \frac{\sin{2x}}{2} + \frac{\sin{3x}}{6} + \frac{\sin{5x}}{10} + \cdots \right)
\end{equation}
\end{widetext}
```

Revtex is leaving a lot of gaps between the equations, which is not looking good as well.

I am using the following document class statement:

LaTeX:

`\documentclass[reprint, amsmath, amssymb, aps, prl]{revtex4-2}`
