Calc `defmath' is not mentioned in the Org manual or on Worg, so I
suggest the attached patch for the Org manual.

Note that you can also use two org-specific flags @code{T} and @code{t} for

+You can add your own Calc functions defined in Emacs Lisp with @code{defmath}
+and use them in formula syntax for Calc.
