U�ytkownik "Karolina" <karc...@poczta.onet.pl> napisa� w wiadomo�ci news:d2p4kf$fjj$1@news.onet.pl... > Hej! Mozecie pomoc mi z tym zadaniem? Bo mi nie wychodzi... > cos(5/6pi+4x)-cos(5/6pi-4x)=sin150stopni > Pomozcie!!! A nie mo�na po prostu brutalnie? sin (150 stopni) = sin (5/6pi), oba kosinusy rozpisa� w/g wzor�w z ksi�zki (jako cos(a+b)), troch� si� skr�ci (uwa�aj na znaki !) i przynajmniej mnie wychodzi: sin(4x) = 1/2, dalej ju� wiesz. Albo si� pomyli�em. Antek
