Math & Science ⇒ LATEX-AMS generated from MathType fails to compile

[4fingers]

Hi,

I have created a simple equation using MathType 6.9 and exporting it to "AMSLaTeX" or "AMSTeX" results in errors from my LaTeX document. However, exporting it as "LaTeX 2.09 and later" works perfectly.

Before I start complaining to MathType that they might have a bug in their program I wanted to make sure I wasn't doing anything silly.

A basic example of the AMS LaTeX breaking is shown in the following document:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\usepackage{amsfonts}
\begin{document}

\end{document}

The attached simple.log file shows the errors generated from the above LaTeX file.

Any idea how I can get the AMS LaTeX to correctly generate the Equation?

Thanks

The command \rho for the Greek small letter ρ (or \varrho for ϱ) requires math mode. But your example tries to typeset it in text mode.

Code: Select all

\documentclass{article}
\usepackage{amsmath}

\begin{document}
  $\frac{\text{P}}{\rho}{\text{u}^2}$

  $\frac{P}{\rho}{u^2}$
\end{document}

Somethings is wrong with the export from MathType.

Thanks Thorsten, that reply was very helpful. Now that I know I am not doing anything wrong in my LaTeX document I will try focus my attention on fixing it within MathType.

Perhaps you should type your mathematical stuff directly in LaTeX instead of relying on problematic export by third party tools. What you presented was very basic and if there are already problems with such basics, fixing problems in more complicated expressions can become very time consuming. Writing math in LaTeX is no sorcery. Furthermore the exported code in your example has many superfluous braces which can make longer code very messy so that its more difficult to spot errors.
