I am currently working on a paper and require an equation with e^x. I tried using the suggested layout of $\exp(x)$ but my output only shows an equation with exp(x) in the PDF output. Is there something that I am doing wrong is is there a specific package I need to use?

Any help would be appreciated.

I think you may have misunderstood what you have been told.

`\exp(x)`

is not an alternative to`e^{x}`

in LaTeX, exp(x) is an alternative toe^{x}in maths and physics etc.The exp(

x) notation is useful wherexis some large or complicated expression, e.g.:Which I certainly think is a big improvement over:

The

e^{x}notation is useful wherexis something nice and small, like, well:So LaTeX supports both,

`\exp(x)`

for exp(x) and`e^{x}`

fore^{x}.`\exp(x)`

is not a LaTeX shorthand (longhand?) for`e^{x}`

=e^{x}.
