LaTeX

LaTeX (pronounced lahhh-tek) is a mathematical markup language that makes it possible to describe math things in plain text and have them automatically rendered to images. For example,

<latex>
F(x,y)=0 ~~\mbox{and}~~
\left| \begin{array}{ccc}
  F''_{xx} & F''_{xy} &  F'_x \\
  F''_{yx} & F''_{yy} &  F'_y \\
  F'_x     & F'_y     & 0 
  \end{array}\right| = 0
</latex>

produces:

F(x,y)=0 ~~\mbox{and}~~
\left| \begin{array}{ccc}
  F''_{xx} & F''_{xy} &  F'_x \\
  F''_{yx} & F''_{yy} &  F'_y \\
  F'_x     & F'_y     & 0 
  \end{array}\right| = 0
