There should really be a page explaining the different ways to create
symbolic variables. For every person using sage for research, there are
probably ten who are just using it as a glorified calculator.
It took me two or three years to realize that I should be using
SR.symbol('x', domain=...) instead of var('x') and assume(). Or R<x> =
foo, or QQ['x'], or...
There are plenty of examples, just no one place explaining the
differences and what each one does.
