Jose brings up a good point below.
Why aren't we simplifying e.g. sin(234*%pi/11) => -sin(3*%pi/11) ?

Bonjour, la commande :
bfloat(cos(400.0*%pi/9.0)-cos(4.0*%pi/9.0))
(notez que 400 pi / 9 est ?gal ? 4 pi / 9 modulo 2 pi)
ne me renvoie pas 0 ; pas plus qu'une ?valuation symbolique de cos (400
pi / 9) - cos (4 pi /9 ) , ou du moins dans ce cas, je n'ai pas trouv?
la commande le permettant...
Y a-t-il une explication ? ?a ?
