# Different fonts for texts and equations

I've been trying to set a separate font for text contents and equations. However, both the math and text fonts remain the same. Below is the typesetting I am using in my own doc.style. Can anyone help how can I restore the beautiful fonts for only the equations ? Thanks.

• Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem.

• Since your code does not appear to contain any math material, it's not possible to tell what may be going on. As @DG' has noted, it's essential that you provide some fully compilable code that actually generates the issue you wish to fix. For sure, if I prefix \documentclass{report} and affix \begin{document} Hello World. $E=mc^2$ \end{document} to your code in order to make it compilable and produce some output, both the text font and the math font are fine (viz., the default, Computer Modern). In short, don't expect us to be able to simply guess what it is that you're doing.

• Thank you, coded included in the main question. Mar 20 at 15:09

Try this :

\documentclass{standalone}
\usepackage[paper=A4]{}
\usepackage{mathrsfs,amssymb}
\usepackage[intlimits]{empheq}
\begin{document}
normal text
\begin{math} a^2 + b^2 = c^2 \end{math}
more text
\end{document}


• Thank you but it didn't work for me. I've included the packages used in the style file in case if you can look at it again. Thanks Mar 21 at 6:22
