Flash library for math equations and graphs, like DragMath and PetitGrapheur

I'm working on e-learning solution and our project requires free or commercial component for math formulas and graphs rendering.

Use cases are:

• built in flash or flex;
• compose math equlation like in in http://www.dragmath.bham.ac.uk/demo.html
• graph rendering like in http://xxi.ac-reims.fr/javamaths/Grapheur/PetitGrapheur.html
• pure client side solution;

So far I found:

1. http://code.google.com/p/mathmlformula/ - really cool, but UI controls are missing (controls like in DragMath).
2. http://validi.fi/latex2flash - but it requires server-side access.
3. http://www.freemathhelp.com/equation-grapher.html - nice graph renderer, mostly satisfy. Need to fix operation priorities (parenthesis).

Please help me with your experience.
