Here are some example latex equations:

• \frac{a}{b} is a fraction with a over b
• \sqrt{a} is the square root of a
• \int_{lower limit}^{upper limit} integrand \, dx gives an integral. The \, command isn't necessary but it makes the spacing look nice.
• \newcommand{\newcommandname}[number of arguments]{what the command should do} This lets you reuse particular forms.
• a^{b} gives a raised to b
• a_{b} gives a with a subscript of b
• \text{regular text here} This lets you type in words that aren't interpreted as symbols
• \color{red, green, blue, cyan, magenta, yellow, or black} will change the color of the rest of the current argument
• \color[rgb]{a, b, c} will change the color to something with a amount of red, b amount of green, and c amount of blue. a, b, and c need to be numbers between 0 and 1.
• \uc{color name}{item} will colorize that item
• Note: if you know Mathematica syntax better, try this page
