What Is a Cross Product?

The cross product (also known as the vector product) is a binary operation on two vectors in three-dimensional space. It produces another vector that is perpendicular to both original vectors.

If:

Vector A = (A₁, A₂, A₃)
Vector B = (B₁, B₂, B₃)

Then the cross product A × B is calculated using the determinant of a 3×3 matrix:

| i j k |
| A₁ A₂ A₃ |
| B₁ B₂ B₃ |

The result is:

A × B =
( A₂B₃ − A₃B₂ ,
A₃B₁ − A₁B₃ ,
A₁B₂ − A₂B₁ )

This resulting vector is perpendicular to both A and B.

Practical Example

Let’s calculate:

Vector A = (2, 3, 4)
Vector B = (5, 6, 7)

Using the formula:

C₁ = (3×7 − 4×6) = (21 − 24) = -3
C₂ = (4×5 − 2×7) = (20 − 14) = 6
C₃ = (2×6 − 3×5) = (12 − 15) = -3

So:

A × B = (-3, 6, -3)

Our Cross Product Matrix Calculator performs this instantly and without mistakes.

Properties of Cross Product

Understanding these properties helps verify results:

• A × B = −(B × A)
• A × A = 0
• Result is perpendicular to both vectors
• Magnitude = |A||B| sin(θ)

Where θ is the angle between the vectors.
