 mathma18@hotmail.com _ Is it possible to express or expand _ sin(x*y) in terms of sin(x) and sin(y)?
 angus_prune@bigfoot.com _ My first instinct is to say, "No, because _ it would be dimensionally incorrect." ;) !
 anonymous@anonymous.com _ no : suppose exists f / sin(xy) = f(sin(x),sin(y)). sin x = sin pi.x/pi = f(sin pi, sin x/pi) = f(sin 0,sin x/pi) = sin 0x/pi = 0
