Cross Product Calculator

Calculate the cross product of two 3D vectors and related properties.

Vector A

A = (1, 2, 3)

Vector B

B = (4, 5, 6)

Cross Product Formula

A x B = (AyBz - AzBy, AzBx - AxBz, AxBy - AyBx)

x-component:

(2)(6) - (3)(5) = -3

y-component:

(3)(4) - (1)(6) = 6

z-component:

(1)(5) - (2)(4) = -3

Cross Product A x B

Properties of Cross Product

  • The result is perpendicular to both input vectors
  • A x B = -(B x A) (anti-commutative)
  • A x A = 0 (zero vector)
  • |A x B| = |A||B|sin(theta)

About Cross Product

Definition

The cross product of two vectors in 3D space is a vector that is perpendicular to both input vectors. Its magnitude equals the area of the parallelogram formed by the two vectors.
