# Large letter in align environment

I have the following formula in an align environment

\documentclass[12pt]{article}

\begin{document}
\begin{align}
\hspace*{5mm}w_{c} = \large{\textit{f}} _{w,c} * \frac{log(|C|)}{\int _{w,C}}
\end{align}
\end{document}


But I want that function sign f to be much larger. I can do this with \mathcal, but I cannot manage it with ordinary letters.

• Unrelated: the log should be coded \log. – Bernard Aug 16 at 9:43
• Exactly why? It seems very strange – daleif Aug 16 at 9:44
• @daleif Perhaps it's some kind of operator. – Steven B. Segletes Aug 16 at 10:13
• @StevenB.Segletes then they are looking for a marked integral symbol (there are several of these) not an f – daleif Aug 16 at 12:03

Put the size specification inside the \textit.
