Mathematics notation

This filter allows you to type in any standard Tex within dollars signs, anywhere in Moodle (including forums etc) like this:

$$$ \Bigsum_{i=\1}^{n-\1}\frac1{\Del~x}\Bigint_{x_i}^{x_{i+\1}}\{\frac1{\Del~x}\big[(x_{i+1}-x)y_i^{5$\star}\big]-f(x)\}^\2dx$$$

and it will be displayed efficiently like this:

$$ \Bigsum_{i=\1}^{n-\1}\frac1{\Del~x}\Bigint_{x_i}^{x_{i+\1}}\{\frac1{\Del~x}\big[(x_{i+1}-x)y_i^{5$\star}\big]-f(x)\}^\2dx$$

The algebra filter is similar but allows a more informal calculator-like notation within @@@ characters:

@@@cosh(x,2)-sinh(x,2)=1@@@

@@cosh(x,2)-sinh(x,2)=1@@
