What's the reasoning for making this a text post instead of submitting the URLs directly?
Thanks. I already use MathJax and it is good. Is there an equivalent to MathJax for mathematical charts (e.g. y = f(x) rather than a random scatter) and/or for plane geometry (e.g. calculate angle A in the shown triangle etc.)?
