[Tex/LaTex] e^{…} vs \exp(…) in display mode

math-modemath-operators

In terms of readability as well as correct syntax, what is more preferred in mathematical equations: e^{...} or \exp(...) — and why?

For instance, e^{x^2/(4t)} or \exp(x^2/(4t)). The latter is easier in that I can directly convert this expression into Mathematica for instance and then manipulate it, whereas the former I must convert each instance of e manually to E. On paper, the former is easier to read.

Typographically, depending on the argument, when should one use e^{x^2/(4t)} or when should one use \exp(x^2/(4t))?

Let's see what Ellen Swanson in page 20 of her classic Mathematics into Type has to say about this:

These two ways should work also in ConTeXt:

$\displaystyle\sum_{i=1}^n a_i$

$\sum\limits_{i=1}^n a_i$

Probably the second form is preferable, although I usually advise not to put limits above and below in in-line math formulas.

[Tex/LaTex] Left-aligned display math mode

My first thought (you didn't wait long enough to get my answer) was to set the math left aligned in an \hbox that was shorter than the \displaywidth by twice the indentation value:

\newdimen\mydisplayboxwidth
\newdimen\mydisplayindent
\mydisplayindent 2\parindent % 
\noindent OK:
$$\mydisplayboxwidth\displaywidth
  \advance\mydisplayboxwidth-2\mydisplayindent
  \hbox to \mydisplayboxwidth
    {$\mathsurround0pt \displaystyle a + b = c$\hss}
\eqno(1)$$
and so continues the paragraph.
\bye
