Drupal modules are pretty cool. I’ve just found a Tex filter that would allow a teacher to post mathematic formulas in text.
So this text “f(x)=\int_{-\infty}^xe^{-t^2}dt” would turn into
[tex]f(x)=\int_{-\infty}^xe^{-t^2}dt[/tex]
So this text “f(x)=\int_{-\infty}^xe^{-t^2}dt” would turn into
[tex]f(x)=\int_{-\infty}^xe^{-t^2}dt[/tex]
The filter also can generate an iFrame with a graph. Here’s a sin(x) sample:
[graph]sin(x)[/graph]
