3D cross product of two vectors produces third perpendicular vector, used for normal calculations, torque, angular momentum.
Trin-for-trin guide
- 1Input two 3D vectors (x,y,z)
- 2Calculate a × b using determinant method
- 3Result shows magnitude and direction
Løste eksempler
Input
a=(1,0,0), b=(0,1,0)
Resultat
a×b = (0,0,1) (perpendicular to both)
Almindelige fejl at undgå
- ✕Forgetting right-hand rule
- ✕Confusing with dot product
Ofte stillede spørgsmål
Does order matter?
Yes, a×b = -b×a (anticommutative).
