LaTeX is a document preparation system written by Don Knuth (TeX) and extended by Leslie Lamport. It is a powerful, and free, way to generate professional, dynamic documents.
LaTeX on Pratt Pundit
The Basics
Pratt Pundit can process most basic \(\LaTeX\) structures by using \( and \) or math tags around \(\LaTeX\) code. For example,
\(q(t)=q(t_0)+\int_{t_0}^ti(\tau)~d\tau\)
can be created using
<center>
\(q(t)=q(t_0)+\int_{t_0}^ti(\tau)~d\tau\)
</center>
Equations can also be inline - for instance, \(c^2=a^2+b^2-2ab\cos(\theta)\) is an equation. The code for that is:
Equations can also be inline - for instance, \(c^2=a^2+b^2-2ab\cos(\theta)\) is an equation.
Equation Lists
For multiple equations one after the other, use the \begin{align} environment. This will allow you to line equations up by placing an ampersand just before the symbol on each line you want as the alignment character. Use \\ to go to the next equation. For example,
<center>\(
\begin{align}
q(t)&=q(t_0)+\int_{t_0}^ti(\tau)~d\tau\\
a&=\left(\frac{dv}{dt}\right)
\end{align}
\)</center>
produces:
You can also have multiple equations in the same row:
<center>\(
\begin{align}
L_1&=10~\mbox{mH} & R_1&=15~\mbox{k}\Omega & C_1&=22~\mu\mbox{F}\\
L_2&=18~\mbox{mH} & R_2&=22~\mbox{k}\Omega & C_2&=17~\mu\mbox{F}
\end{align}
\)</center>
produces:
Arrays
Arrays work perfectly well in Pundit - as long as you don't try to stretch them:
Known Issues
- RESOLVED: LaTeX on Pundit didn't know "unnumbered" versions of things, but know it does - behold!
<center>\(
\begin{align*}
e^x&=\sum_{k=0}^{\infty}\frac{x^k}{k!}
\end{align*}
\)</center>
will cause:
which is correct! Note that using the unstarred version produces:
<center>\(
\begin{align}
e^x&=\sum_{k=0}^{\infty}\frac{x^k}{k!}
\end{align}
\)</center>
to get:
- LaTeX on Pundit does not process changes to the
\arraystretchvariable - so arrays cannot be stretched or contracted.
FAQ
What did I do wrong?
Generally, LaTeX will try to tell you - look closely at the error message LaTeX gives you
What is Underfull hbox -10000?
It's a warning that something is a bit thin - generally a table or a figure. Don't worry about these at all.
Why does LaTeX think my align or align* environment is messed up?
To continue: "I have checked it thousands of time and it looks good to me!" Make sure there are no blank lines within the environment. For some reason align hates those. The following, for example, causes problems:
\begin{align}
a\\
b
\end{align}
Also - it may be in a line above the end of the align environment. You can use % in front of a line of LaTeX code to turn that whole line into a comment - doing that, you can find which line is having a bad day and correct it.
My \pagebreak doesn't...page...break Why?
Make sure there is a blank line after the \pagebreak command; that is:
blah
\pagebreak
more blah
How can I double space?
Basically, include the following two lines between the \documentclass and the \begin{document}[1]:
\usepackage{setspace}
\setstretch{2.0}
The MIT page has more options, including adding different spacing to sections of a document.
How do I get a $ Symbol
For the characters that LaTeX uses as code ($ and { or }) you need to issue the command to print those - in other words, \\$ \{ and \} are the commands to print those individual characters. For example, the code:
\$\{10,000\}
will produce \( \$\{10,000\} \)
Questions
Post your questions by editing the discussion page of this article. Edit the page, then scroll to the bottom and add a question by putting in the characters *{{Q}}, followed by your question and finally your signature (with four tildes, i.e. ~~~~). Using the {{Q}} will automatically put the page in the category of pages with questions - other editors hoping to help out can then go to that category page to see where the questions are. See the page for Template:Q for details and examples.
