# Math 181 Honors Calculus, Fall 2008, Prof. Bell

### Did 'ya Know?

This week I thought that I'd demonstrate how to add 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 $\doteq$
