:If Cd had a unit, say it was an energy which represented some relevant value for a given material, then it would not be correct to say that it was half as much, just because 1/2 came into the equation. But if it has no units, then it is just a constant saying something about the material, and then the 1/2 could in principle be absorbed without changing anything. But as stated above 1/2 actually has physical meaning in the way it enters the equation. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 10:44, 12 January 2022 (UTC) | :If Cd had a unit, say it was an energy which represented some relevant value for a given material, then it would not be correct to say that it was half as much, just because 1/2 came into the equation.

For instance, Coulomb's law works fine whether we write it F = -q<sub1</subq<sub>2</sub>/(4πε<sub>0</sub>r<sup>2</sup>) or F = -kq<sub1</subq<sub>2</sub>/</sub>r<sup>2</sup>. Similarly, if we had a factor of 2 in the gas law for some reason, that would just change the values of the gas constants. |
I've seen the double-struck capital "D" used commonly as a symbol for the Domain of a function (While the double-struck "R" was used for the range in that context) [[Special:Contributions/162.158.63.243|162.158.63.243]] 21:16, 17 January 2022 (UTC) | I've seen the double-struck capital "D" used commonly as a symbol for the Domain of a function (While the double-struck "R" was used for the range in that context) [[Special:Contributions/162.158.63.243|162.158.63.243]] 21:16, 17 January 2022 (UTC) |
