asså när jag använer funktionerna i math.h uniten i c++ blir resultaten fel...

har gjort följande:

double x;

	Label1->Caption = sin(x);

och tex om jag x= 30
då blir svaret 6,366.......osv

men det e fel...sinus 30 skall vara 0.5...
varför blir det så? nån som vet hur man rättar till?

Hmm. RTFM. Eller prova att beräkna sin(pi/6) istället. Den räknar nämligen antagligen med radianer...

EDIT: Fast det vete sjutton förresten. -1 < sin(x) < 1 < 6,nåt...
