LaTeX

\LaTeX is a very powerful language and allows one to type very nice mathematics in a way that would be difficult to do any other way. It is what provides the mathematics on this site. How else could one show

    \zeta(n)=\underbrace{\int_0^1 \cdots \int_0^1}_{n}\dfrac{\prod_{i=1}^n dx_i}{1-\prod_{i=1}^n x_i}

But \LaTeX will do more than that and also provide graphics. See the diagram in Monday 10 May or how about these:

    \setlength{\unitlength}{0.5cm} \begin{picture}(5,2) \put(5,0){\line(-1,0){5}} \put(0,0){\line(1,1){2}} \put(2,2){\line(3,-2){3}} \put(-0.5,-0.1){\small A} \put(1.9,2.1){\small B} \put(5.1,-0.1){\small C} \put(4,0.1){\tiny 30} \qbezier(3.8,0)(3.9,0.55)(4.1,0.55) \put(0.6,1){\footnotesize 2} \put(3.6,1){\footnotesize 3} \put(2.3,-0.6){\footnotesize 5} \put(6,-0.2){\tiny \shortstack{t\r\i\a\n\g\l\e}} \end{picture}

    go on – spot the deliberate error 😕

or

    \setlength{\unitlength}{1mm} \begin{picture}(60,40) \put(30,20){\vector(1,0){30}} \put(30,20){\vector(4,1){20}} \put(30,20){\vector(3,1){25}} \put(30,20){\vector(2,1){30}} \put(30,20){\vector(1,2){10}} \thicklines \put(30,20){\vector(-4,1){30}} \put(30,20){\vector(-1,4){5}} \thinlines \put(30,20){\vector(-1,-1){5}} \put(30,20){\vector(-1,-4){5}} \end{picture}

See here for a good tutorial on \LaTeX graphics
