Problem with display-only JME functions

[William Haynes]

I am having trouble getting these functions to work as I think they should.  For example, if I put $\var{diff(x,y,1)}$ into a problem statement, Numbas generates variables for x and y instead of rendering the partial derivative.  Am I misunderstanding something?

Thanks,

Will

My understanding is these work in the simplify environment, i.e. try $\simplify{diff(x,y,1)}$

Yes, \var is for substituting in values, and \simplify is for displaying expressions.
