Yes, either that (which seems to use the <math.h> sin or cos
functions), or an [until] + [sin] + [tabwrite] routine.  The former is
easier, obviously, and also adds the three guard points automatically
(it also seems to use the same precision of PI=3.14159 that you can
get with floats in Pd patches).

If you want the code, look for the function garray_dofo in g_array.c
