LaTeX

I came across this wonderful blog post about writing equations in a wordpress.com blog. I also found this post on a program that converts .tex files into wordpress.com posts.

Sample techniques below:

Inline

blah blah $\int_{-\infty}^\infty e^{-x^2}\,dx=\sqrt\pi$ blah blah

In a Box

 $\int_{-\infty}^\infty e^{-x^2}\,dx=\sqrt\pi$

Align Center

$\displaystyle\int_{-\infty}^\infty e^{-x^2}\,dx=\sqrt\pi$

Multiline

$\setlength\arraycolsep{2pt}\begin{array}{rl} \displaystyle\int_{-\infty}^\infty e^{-x^2}\,dx&\displaystyle=\sqrt\pi,\smallskip\\ \displaystyle\int_{-\infty}^\infty e^{-ax^2}\,dx&\displaystyle=\int_{-\infty}^\infty e^{-y^2}\frac{dy}{\sqrt a}\smallskip\\ &\displaystyle=\sqrt{\frac\pi a} \end{array}$

Equation Numbering

 $\displaystyle C(S,t)= S N(d_1) - N(d_2) K e^{-rt}$ (1)

Numbering applied to two rows

 $\setlength\arraycolsep{2pt}\begin{array}{rl} \displaystyle d_1&\displaystyle=\frac{\ln(S/K) + (r + \sigma^2/2)(T - t)}{\sigma \sqrt{T - t}}\bigskip\\ \displaystyle d_2&\displaystyle=d_1 - \sigma \sqrt{T - t} \end{array}$ (2)
