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
$$ x^2y_3+6=z_2^7$$
You can also write fractions this way:
$$ \frac{a}{b} $$
producing
$$ \frac{a}{b} $$
You can make an integral like this:
$$ 2\pi \int_a^b f(x) dx $$
producing
$$ 2 \pi \int_a^b f(x) dx $$
You can make a sum, and limits, like this:
$$ \lim_{N \rightarrow \infty} \sum_{i=1}^{N} \frac{1}{i} = \infty $$
producing
$$ \lim_{N \rightarrow \infty} \sum_{i=1}^{N} \frac{1}{i} = \infty $$
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 $ \lim_{N \rightarrow \infty} \sum_{i=1}^{N} \frac{1}{i} = \infty $ 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
$$ \begin{pmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{pmatrix} $$
If you have a symbol in mind and want to know the latex for it, draw it in the “deTexifyer”:
