It's sad and contrary to HP's previous philosophy, but more and more students are expecting to get results like this, so even HP is faking it now.

Strangely (on the real calc, with "intelligent math" OFF), SIN(π*1) also returns 0, but SIN(π+0) doesn't!

EDIT: Maybe it should be considered a bug: "intelligent math" being used in some cases (and inconsistently so) even when the option is disabled.
