I can't find a way to use the PI constant in the equation editor other than with "acos(-1)" in radients mode,
which is not very practical.
Please EDIT the equation, move the cursor where you want to insert it, turn to lower case and press [g][P]. Works like a charm.
(This will work with other constants in full analogy, BTW.)
