## Moodle and

is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. is the de facto standard for the communication and publication of scientific documents. is available as free software.

Moodle comes with the ability to handle . Check that your administrator has enabled it.

To include code in Moodle, use the following:

$$Your-latex-Code$$

`So $$A=\pi r^2$$`

becomes

## Symbols

If you type $$\alpha, \beta, \gamma$$ into Moodle you get .

` Knowing this you can write formulas such as $$A = \pi r^2$$ `

Knowing this you can write formulas such as

`Note the difference between $$\sigma and \Sigma$$.`

Note the difference between and

`You can guess the names of most of the symbols you need...`

$$\pm,\le, \neq, \ge$$

You can guess the names of most of the symbols you need…

`There are lots of other symbols: $$\forall , \leftarrow, \Rightarrow, \infty$$, $$\cos (2\theta) = \cos^2 \theta - \sin^2 \theta$$`

There are lots of other symbols: ,

## Functions, Fractions and Derivatives

You’ve already seen how to write superscripts. Use the underscore for subscripts: n_ij

Copper Sulphate: $$CuSO_4$$ :

Use braces { } for clarity:

Fibonacci Sequence: $$F_n = F_{n-1} +F_{n-2}$$ :

Here are some fractions

$$\frac{x+y}{y-z}$$ :

$$\frac{\frac{1}{x}+\frac{1}{y}}{y-z}$$

:

You can probably guess what \sqrt does, so that gives us

$$x = \frac{-b \pm \sqrt{b^2 – 4ac }}{2a}$$

Which you can copy and paste when you need it.

Here’s how to do derivatives

$$y = x^2$$

$$\frac{dy}{dx}=2x$$

## Brackets

Note the use of \left and \right to size the brackets correctly

$$\frac{x+y}{y-z}$$

$$(\frac{x+y}{y-z})$$

$$\left(\frac{x+y}{y-z}\right)$$
