I don't see why you say that the differential operator on the palette
doesn't work. If you paste it in a notebook and then fill in x and the
expression and then evaluate, it will work.

Otherwise, you could do something like:

d[x_] = Function[expr, D[expr, x]];

2 x

Hi All

My students have asked me whether it is possible to define the operator
df[x]/dx for differentiation rather than D[f[x],x]. The operator is
available in a palette but it does not seem to do anything other than for
display only.

Example: d/dx(x^2)=2x rather than D[x^2,x]=2x.

Am I missing something?

Mr. Chee
