## Proper form of the "dx"Edit

I thought the proper form was to distinguish it somehow from the product of two variables named "d" and "x". One way to do this is with \mathrm{d}x instead of dx. With that in mind, I boldly went ahead and changed the article. Revert if I overstepped!—GraemeMcRaetalk 21:23, September 30, 2010 (UTC)

## \operatorname{d}\! instead of \,\mathrm{d} Edit

It would be better to use \operatorname{d}\!x (e.g. $\int\operatorname{f}\left(x\right)\operatorname{d}\!x$) instead of \,\mathrm{d} (e.g. $\int\operatorname{f}\left(x\right)\,\mathrm{d}x$), because \operatorname already inserts a space before the "d", and $\operatorname{d}\!x$ originates from $\Delta x$[1]
