I want to cram all of these calculus notes into just one page, so all of the whitespace which display-math-mode wastes is a big no-no; yet, I still do need the visual style which display-math-mode offers, formatting this whole reference sheet in just in-line horizontal math mode would look awful.

Is

	Leibniz notation: $\vcenter {\hfuzz = \hsize \hsize = 0 pt $$\displaystyle {\rm d}f \over {\rm d}x$$}$

of any use ?
