Exemple Résolu
Cross product of (2,3,4) and (5,6,7).
- 01x: 3×7 - 4×6 = 21 - 24 = -3
- 02y: 4×5 - 2×7 = 20 - 14 = 6
- 03z: 2×6 - 3×5 = 12 - 15 = -3
- 04A × B = (-3, 6, -3)
- 05|A × B| = √(9+36+9) = √54 ≈ 7.3485
Questions Fréquentes
What is the cross product?
The cross product of two 3D vectors produces a vector perpendicular to both inputs. Its magnitude equals the area of the parallelogram formed by the two vectors.
Does the cross product work in 2D?
The cross product is only defined for 3D vectors. In 2D, you can treat vectors as 3D with z=0, and the result will point entirely in the z direction.
What does the magnitude represent?
The magnitude of A × B equals |A|×|B|×sin(theta), which is the area of the parallelogram spanned by the two vectors.
