You can typset your assignments beautifully in LaTeX . Here’s a quick start guide once you’ve got yourself into some latex editing software and have a document open (see Resources for some info on getting the software going).

To add an equation to your latex document, as a separate line, you surround your math with $$ at the beginning and $$ at the end. So, you write

`$$ YOUR MATH HERE $$`

You can use symbols like + x – and for exponents you can write ^. For subscripts you can use _. So for example,

`$$ x^2y_3+6=z_2^7 $$`

produces

You can also write fractions this way:

`$$ \frac{a}{b} $$`

producing

You can make an integral like this:

`$$ 2\pi \int_a^b f(x) dx $$`

producing

You can make a sum, and limits, like this:

`$$ \lim_{N \rightarrow \infty} \sum_{i=1}^{N} \frac{1}{i} = \infty $$`

producing

Here’s a real pro tip: if you want your math inline, use $ and $ (single dollars) to surround it. So for example,

`I was trying to evaluate $ \lim_{N \rightarrow infty} \sum_{i=1}^{N} \frac{1}{i} = \infty $ when a pig flew.`

produces

I was trying to evaluate when a pig flew.

Finally, you can make a matrix this way:

`$$ \begin{pmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{pmatrix} $$`

and you’ll get

If you have a symbol in mind and want to know the latex for it, draw it in the “deTexifyer”:
