Hi David Park
Thank you for your reply. I tried the d/dx operator (like what we see in
Calculus textbooks) in the Classroom Assistant palette but it seems to be
for display only. (Am i missing something here?) I guess the solution is
to format it to behave like a differentiation operator. Any ideas on that?
We would like d(f[x])/dx to function in the same way as D[f[x],x].
Thank you all for your suggestions.
Regards

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]];
d[x][x^2]
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 f=
or
display only.
Example: d/dx(x^2)=2x rather than D[x^2,x]=2x.
Am I missing something?
Thanks
Mr. Chee
