Dear All,
now I'm having a problem with IS(). I'd like to know whether
sin(x)/cos(x)=tan(x). I'm writing:
IS(EQUAL(sin(x)/cos(x),tan(x)));
Maxima reports an error:
MACSYMA was unable to evaluate the predicate:
ERREXP1
-- an error. Quitting. To debug this try DEBUGMODE(TRUE);)
Is this the normal behaviour?
TIA, Zoltan
