It's not sure what your needs are. In an on-line exam, the user enters the
equations/math expressions. There is no plug-in for entering math expressions
or symbols. Expressions must be entered in "ASCII" format:
(2*x^3+cos(e^x))^2
for example.
I've developed a series of JavaScripts to interpret such "user friendly"
input and convert to proper JavaScript:
pow(2*pow(x,3)+cos(exp(x)),2)
I've also developed techniques for evaluating the correctness of such
expressions using JavaScript.
