Howdy all.  I'm the guy who came to tell you all about this internet tool.  I just did some major changes to the looks of this site, so if something looks new and different, don't be afraid.  Some of the buttons that used to be found on the top of the page are now at the bottom.  'Edit' is one of these such buttons.  If something really doesn't work, just leave me a comment here and I'll check in throughout the next couple of weeks.

This week I thought that I'd demonstrate how to add an ellipses in a LaTeX equation.

Nobody wants to see small curves like these...

<math>
 
<math>
\int_a^b ( \frac{1}{a^2 - x^2} ) dx ~or~ | \frac{1}{1+\frac{1}{1+\frac{1}{x}}} |
+
\begin{align}
 +
\sum_n &= 1 + 2 + 3 + ... + n + ... + \infty
 +
&= 0 + 1 + 2 + \cdots + n + \cdots + \infty
 +
\end{align}
 
</math>
 
</math>
  
But LaTeX can help! Use \left and \right around parentheses, brackes, pipes, etc...
+
In the first example, three consecutive dots were typed, but the second example uses LaTeX's \cdots command. This stands for center dots. There are also other 'dot' functions.

By the way, did you know that you can align multi-line equations.  Mediawiki is full of formatting markups, and the more you get to know them, the more professional (and readable) you can make your pages look.  View the source for the below equation to find out how to make long equations look nicer.  You might also check out Mediawiki's super-easy [http://meta.wikimedia.org/wiki/MediaWiki_User%27s_Guide:_Using_tables tables].

Math 181 Honors Calculus

Did 'ya Know?

This week I thought that I'd demonstrate how to add an ellipses in a LaTeX equation.

$ \begin{align} \sum_n &= 1 + 2 + 3 + ... + n + ... + \infty &= 0 + 1 + 2 + \cdots + n + \cdots + \infty \end{align} $

In the first example, three consecutive dots were typed, but the second example uses LaTeX's \cdots command. This stands for center dots. There are also other 'dot' functions.

\ldots $ \ldots $ \therefore $ \therefore $
\cdots $ \cdots $ \dagger $ \dagger $
\vdots $ \vdots $ \clubsuit $ \clubsuit $
\ddots $ \ddots $ \doteq $ \doteq $
