Math & Science ⇒ l'Hospital's rule symbol

[rickcjmac]

I saw in Calculus I my teacher used a symbol specific to L'hospital's rule. It was an equal sign with an "H" over it. Is there any way to make that symbol with LaTex code or was that something that my teacher made up just for that class?

Any help is appreciated. Thanks.

The answer to both questions is yes. You can try something like the following:

Code: Select all

\documentclass{report}
\usepackage{amsmath}

\newcommand*\Heq{\ensuremath{\overset{\kern2pt H}{=}}}

\begin{document}

\[ a\Heq b \]

\end{document}

I don't know whether or not that's commonly used, but Detexify didn't come up with a single command for it.

However, it shouldn't be too hard to create using something like the \overset command from the amsmath package. Load that package and try:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\begin{document}
$a \overset{\mathrm{H}}{=} b$
\end{document}

(Or remove the \mathrm part if you want an italicized H, etc.

Darn, scooped again!

Such basics are explained in every good reference guide like latex2e-help-texinfo [1]. You can build that symbol by stacking two single characters.

Code: Select all

\documentclass[11pt,a4paper]{article}
\usepackage{amsmath}

\begin{document}
  \[
    \lim_{x\to 0}\frac{\sin x}{x}\stackrel{\text{H}}{=}\frac{\cos x}{1}=1
  \]
\end{document}

The amsmath package was only used to create an upright »H« with the \text{...} command. The rest is vanilla LaTeX.
