Add the LaTex string in the body of the post. Surround the string by double dollar signs.
EX1:$$y = 3.02 cos (\omega t + \theta)$$
$$y = 3.02 cos(\omega t + \theta)$$
EX2:$$y = k _{0} + k_{1} \left[ \frac {\beta - 1}{ 2x + \alpha t} \right]$$
$$y = k _{0} + k_{1} \left[ \frac {\beta - 1}{ 2x + \alpha t} \right]$$
You can use an online formatter gui such as this tool at codecogs.com to generate the expression. This site will generate the syntax for Latex, and render as html and as a graphic. Here is the same equation rendered in html. (it is slower to render, as it links to codecogs.)
