# How can I restore LaTeX standard font for math equations in a sty file?

I am using the style file for classic thesis, which can be downloaded in this link and can be viewed in this link. I like everything about this style file except the font used for math equations. How can I modify the classicthesis.sty such that math equations are printed the same as the standard LaTeX math?

• Can you show how you call classicthesis? The options you pass to the package are needed. – egreg Mar 29 '13 at 9:24

This is what I get from this simple example:

\documentclass[11pt,a5paper,footinclude=true,headinclude=true]{scrbook}
\usepackage[T1]{fontenc}
\begin{document}
This is inline math $a+b=c$ and a displayed formula follows:
$\int_{-\infty}^{\infty}e^{-x^2}\,dx=\sqrt{\pi}$
\end{document}


The font used for math is MathPaZo, which is tailored to accompany the default Palatino text font.

If I change the example in the following way

\documentclass[11pt,a5paper,footinclude=true,headinclude=true]{scrbook}
\usepackage[T1]{fontenc}
\begin{document}
This is inline math $a+b=c$ and a displayed formula follows:
$\int_{-\infty}^{\infty}e^{-x^2}\,dx=\sqrt{\pi}$
\end{document}


(note the eulermath option), I get Euler Math for the formulas.

If instead you load lmodern after classicthesis

\documentclass[11pt,a5paper,footinclude=true,headinclude=true]{scrbook}
\usepackage[T1]{fontenc}
This is inline math $a+b=c$ and a displayed formula follows:
$\int_{-\infty}^{\infty}e^{-x^2}\,dx=\sqrt{\pi}$

• I edited in eulermath, hope you don't mind. – Scott H. Mar 29 '13 at 20:42
• @egreg, I want to use your solution but the problem is after using lmodern the font of text is also changed and I'm happy with the text font. How can I used your solution while maintaining the normal text font? – Pouya Oct 7 '13 at 15:15
