At first I thought that roman d was reserved for the exterior derivative and italic d for scalar differentials.
That is, one would have df for the exterior derivative of function f but write dy/dx in regular calculus.
But the author of the wikipedia article http://en.wikipedia.org/wiki/Differential_(infinitesimal ) has used roman d for dy/dx. Is this just a matter of author's taste? Or am I missing a subtle distinction?
