The task is to document that the r-coordinate lasts from 10 to 100 m.
What would be a good way to write this down? I thought about the following examples
r = 10 to 100 [m]
r = [10 - 100 [m]]
r = 10 - 100 [m]
r = 10 [m] - 100 [m]
r = [10 - 100] [m]
Any further/better ideas? I could not really find any standard or something which recommends something. I am aware of the sunits siunitx ... but it does not use square brackets. Am I just wrong here to use it?
PS: Is there a way to write tex using mathjax? I would assume so.
