$$a^2+b^2=c^2$$

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

$$a^2+b^2=c^2$$

Paul's Test

$$2+3=5$$

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.
