I'm reading calculus.py (this is probably the best way to learn SAGE).
This statement seems wrong to me:

\sage predefines upper and lowercase letters as global
    indeterminates.

Indeed, I believe only 'x' is predefined.

Component: documentation

This used to be true, but it caused way too much confusion, so we changed it. But forgot to change the docs.
