Math functions need to be within either math tags \(a^2+b^2=c^2\) or double dollar signs $$a^2+b^2=c^2$$. The difference being, the math tag can be used inline and the double dollar sign will put the equation on it's own line and centered on the page.
Example\[a^2+b^2=c^2\]
For expontents, you want to use the ^ symbol. So \(A^x\) would be written like this: A^x. If the exponent contains more than one character, you need to encase them in curly brackets {} so \(A^{xyz}\) would be written like A^{xyz}.
For subscripts, you want to use the _ symbol. So \(A_x\) would be written like this: A_x. If the subscript contains more than one character, you need to encase them in curly brackets {} so \(A_{xyz}\) would be written like A_{xyz}.
Operators work as expected, you can use + - * / within the math tags to add, subtract, multiply and divide. A+B*C/D looks like \(A+B*C/D\)
Symbols such as \(\sqrt{}\) and \(\pi\) are written using LaTeX commands. The two used previously are \sqrt and \pi. A complete list of LaTeX symbols can be found here. So, for example if you typed this within math tags \sqrt[2]{144*2} you would get this:\[\sqrt[2]{144*2}\]
Other Examples
$$\sum f(x) = F(x) + g(x)$$
$$\sqrt{12*32}$$
$$A^2 + B^2 = C^2$$
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
Specific Example taken from this manual
\(A_{sv} = (A_{sd} * Sn_w) - I_{vol}\)
Where:
- \(A_{sv}\) = Average snowmelt volume (depth/unit area)
- \(A_{sd}\) = Average snowpack depth at the initiation of the snowmelt period
- \(Sn_w\) = Typical snowpack water at time of melt
- \(I_{vol}\) = Estimated infiltration volume likely to occur during a 10-day melt period.
