| Feb 23, 2019 at 13:29 | comment | added | Ma Joad | I am afraid that that is not what I have asked. I have already written in my question that I know your formula $ds=\pm \sqrt{(ds)^2}$. But I don't know whether I should put $+$ or $-$ before the square root. I don't think both can be OK simultaneously in a particular situation. | |
