I know many people write $\frac{dx}{dt}$ instead of the IMO better $\frac{\mathrm{d}x}{\mathrm{d}t}$, but in case of $\frac{dd}{dt}$, those italic ds are really confusing. Mind if I edit them to roman style?

| Jul 31, 2017 at 3:22 | comment | added | dts | Thank you for the answer! I have been thinking about this definition too. I have seen many textbooks simply say that v=d/t, and it seems like they have some intuition that I do not. So would this be the "formal" proof that v=d/t (for constant acceleration)? | |
