LATEX Mini HOWTO
On my website, to insert mathematics you have to use . For instance, let's say we wish to insert math within a sentence such as $F=ma$. This can be done by typing \$F=ma\$. Or, if you wish to display an equation by itself out of a sentence such as: $$F=ma$$ Then, enclose the math expression within two dollar signs as follows:
$$F=ma$$
 Greek Symbols
Greek symbols are generally written the way they are pronounced. Thus, $\theta$, $\xi$, $\psi$ can be written as \$\theta\$, \$\xi\$, and \$\psi\$ respectively. Capital Greek letters are written by uppercasing the first letter. Thus, $\Psi$, $\Theta$, and $\Xi$ are typeset as \$\Psi\$, \$\Theta\$, and \$\Xi\$.
 Fractions
A fraction such as $$c=\frac{a}{b}$$ should be coded as
c=\frac{a}{b}
A fraction within a fraction: $$c=\frac{a+\frac{3}{2}}{b}$$ is coded as:
c=\frac{a+\frac{3}{2}}{b}
 Subscripts and Superscripts
Subscripts and superscripts such as $$a=b^{c+\frac{1}{2}}_{d+2}$$ should be written as:
a=b^{c+\frac{1}{2}}_{d+2}
 Text within Equation
The text that appears within an equation such as $$\phi= \frac{\textrm{performance}}{\textrm{price}}$$ should be written as:
\phi= \frac{\textrm{performance}}{\textrm{price}}
 Integrals
An integral such as $$\epsilon=\int_{x=0}^L \left( \frac{x}{5}-\frac{x^2}{2} \right) dx$$ should be coded as:
$$\epsilon=\int_{x=0}^L \left( \frac{x}{5}-\frac{x^2}{2} \right) dx$$
 Sums
The sum of a series $$s=\sum_{i=1}^N (b-a)^i$$ should be coded as
s=\sum_{i=1}^N (b-a)^i

 Large Brackets
Say we want to enclose a fraction within parentheses or brackets. This can be done by preceding the parenthese/bracket with the code \left or \right. For example: $$a=\left[\frac{\partial F}{\partial x}+\frac{\partial G}{\partial y}\right]$$ The latter can be typeset as:
a=\left[\frac{\partial F}{\partial x}+\frac{\partial G}{\partial y}\right]
 Numbered Equations
If you wish to write an equation with an equation number as follows: $$F=ma \tag{23a} \label {eqn:newton}$$ Type the following:

F=ma
\tag{23a}
\label {eqn:newton}

And reference it as Eq. (\ref{eqn:newton}) by typing
Eq. (\ref{eqn:newton})
