For a long time, I was using this way of coding multiple equations (I'm using the book class, in 12pt size):
Now, I prefer using this way :
Which way is better ? How the vertical spacing **should** be defined, in LaTeX ?
What are the advantages and inconvenients of each ? Or is there a better way of doing this ?
My "old" way (using
\\ \\) gives a vertical spacing which feels a bit too wide. The other way (using
\\[18pt]) gives an almost identical output (slightly less wide), but feels a bit more regular.
I need opinions on this, since I may convert all my old codes to the one I currently prefer, but it may be a "mistake".
In case a MWE is needed, here's one (the output of both ways of coding the vertical spacement appears to be identical, but that's because the equations are too simple here.) :
