## Summary

 This image shows some kind of formula that could be converted to TeX. Storing formulas as images makes it harder to change them. TeX also helps making sure that they all use the same font and size. A replacement has been proposed: ${\displaystyle {\sqrt {\frac {a}{b}}}}$ In your article, replace the image with: \sqrt{ \frac{a}{b} }

 Description to be used on the LaTeX wikibook. I created with the following LaTeX source: \documentclass[a4paper,12pt]{article} % New definition of square root: % it renames \sqrt as \oldsqrt \let\oldsqrt\sqrt % it defines the new \sqrt in terms of the old one \def\sqrt{\mathpalette\DHLhksqrt} \def\DHLhksqrt#1#2{\setbox0=\hbox{$#1\oldsqrt{#2\,}$}\dimen0=\ht0 \advance\dimen0-0.2\ht0 \setbox2=\hbox{\vrule height\ht0 depth -\dimen0}% {\box0\lower0.4pt\box2}} \begin{document} \begin{displaymath} \sqrt{ \frac{a}{b} } \quad \oldsqrt{ \frac{a}{b} } \end{displaymath} \end{document}  Date 22 September 2006 Source Own work Author Alessio Damato
