# How increase the font size of an equation with begin{equation}?

I have the following code in RMarkdown that prints an equation like:

# in a LaTeX environment I would write:

\usepackage{amsmath}

\begin{document}
$$\label{eq: eq1} \psi_{j} = \frac{\gamma_{i,j,k}^s}{\sqrt{w_{i,j,n}}}$$
\end{document}



Yet, I would like to increase the font size of the equation. All I found online doesn't work. Can anyone help me?

Thanks!

• What do you mean? Having a bigger font size in equations? Jan 21, 2021 at 20:55
• @Bernard exactly Jan 21, 2021 at 20:57
• put \large before the \begin or \Large or \huge Jan 21, 2021 at 20:58
• @DavidCarlisle it makes all that comes after the equation also bigger, is there a way to limit it only to the equation? Jan 21, 2021 at 21:01
• put it in a group, or put \normalsize after Jan 21, 2021 at 21:04
