### Question about LaTeX on WordPress

Filed under: About — cjohnson @ 10:45 am

Hola.  Does anyone know if there’s a way to do something like eqnarray inside of WordPress’ LaTeX?  If not, what’s the preferred method of listing a long string of equalities?

1. Haha. I just had this problem a few days ago. Personally, I got around it by just starting a new line each time.

latex stuff = stuff
latex = stuff
latex = stuff
latex < stuff

etc.

With the obvious \$ around it. The other fix might be to do a matrix and align things inside of there. (Not that I know how to make the matrix, but I’ve seen other wordpress people do it, so it is possible).

2. $f(x) = \bigg\{ \begin{array}{lcl} 1- \pi x + \sin (\pi x), & \mbox{ if } & x<0,\\ 1+6x -9x^2+4x^3, & \mbox{ if } & x\geq 0. \end{array}$

Maybe you could modify it. Like

$\begin{array}{rcl} 2x+1 &=& 3\\ 2x &=&2 \\ x &=&1 \end{array}$

Hope it works.
