The truth is that, up to now, I have used a template that I created long ago to write my lecture notes. All seems OK, but the only thing that's been bothering me lately is that the integral sign in my equations is not curved (as it should), but it appears rigid and vertical, just like the left integral in this picture:
I really don't know what package I'm missing (or what package I'm importing that does this). I've read several manuals, but can't find the solution to my problem :-(. The packages that I import before the \begin{document}
are:
\documentclass[12pt]{article}
\usepackage{amssymb,amsmath,amsthm,mathabx,wrapfig}
\usepackage[spanish]{babel} % I'm writing lecture notes in spanish!
\usepackage[utf8x]{inputenc}
\usepackage[margin=1.25in]{geometry}
\usepackage{graphics,graphicx,ctable,booktabs}
\usepackage{ccaption}
\usepackage{fancyhdr}
How do I fix this problem?

The problem is in the
mathabx
package, which changes many symbols.You have some possible strategies:
load only two of the three families provided by
mathabx
:revert the integral to the original after having loaded
mathabx
:(some other adjustments may be necessary for multiple integrals)
don't load
mathabx
and follow some of the tricks present on this site for loading only the symbols from it that you really need, for examplehttps://tex.stackexchange.com/a/14406/4427
