[Maxima-discuss] Why is op('diff(f, x)) equal to 'derivative?

[Eduardo O. <edu...@gm...>]

Hi list,

what happens exactly when we run this?

  'diff(f, x);

As far as I know diff(f, x) - without the ' - is equivalent to:

  apply('diff, [f, x]);

but

  op('diff(f, x));

returns "derivative", and I don't know what and where are the
functions that convert 'diff to 'derivative...

  Thanks in advance!
