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))`

?
