A short primer of how reference with an approximation of UWE Harvard style.
Note that it doesn't quite match the quirks of when UWE Harvard uses et.al. after the first time a reference is cited within your text (i.e. this template works according to the rules of the first time a piece is cited within text, rather than the subsequent modifications).
LaTeX is the best way to write mathematics. It completely pisses all over Word. However, it does take some time to get used to so might not be worth your while if you won't write too much. The way I use it is to first download and install a latex editor and then get writing, but I would recommend that you use this website instead since you can get going a lot quicker. The upshot of the whole business is that you type in here and then a pdf is generated with all the equations looking ace. I'll give you some examples.
