Useful Inequalities Cheat Sheet

"Inequality" is a funny concept. An "inequality" per se is almost never useful. And "inequality" is a misleading name for "less than or equal to" relationship, even if technically true in some sense.

This document is of course a list of useful bounds.

Thanks for this. But I wonder if this is of use only if people have already familiriased themselves with the inequality to use it contextually, at which point they mostly have them committed to the memory.
