I only know that we have to make at least one blank line between two adjacent paragraphs.
My question is:
What is the proper way to make use of a blank line ?
For example:
Is it recommended to make a blank line between heading command call, e.g.
\chapter{}
, and the first text content as follows?\chapter{Introduction} In this chapter we ....
or
... that is proven true. \chapter{Limit}
Is it recommended to make a blank line between two consecutive display equations as follows?
\[ \sin x \] \[ \cos x \]
Is it recommended to make a blank line between a sentence and a display equation as follows?
Assume we have \[ \cos x \]
or
\[ \cos x \] that satisfies ...
etc...
Edit 1:
How about
\bigskip
,\vspace{}
? Does each of them needs one blank line before and one blank line after as follows:Yes. This is a book. \bigskip Commander, please open the silo!
or
Yes. This is a book. \vspace{1km} Commander, please open the silo!
