What Is a Cross Vector Calculator?

A Cross Vector Calculator is a mathematical tool that calculates the cross product (vector product) of two vectors in 3D space. The cross product produces a new vector that is perpendicular to both input vectors, following the right-hand rule.

The calculator is commonly used to:

• Find perpendicular vectors
• Compute torque and angular momentum
• Solve physics and engineering problems
• Support 3D geometry analysis

Cross Product Calculation Logic

The calculator uses the standard determinant formula:

Formula:

If$$\mathbf{A} = \langle x₁, y₁, z₁ \rangle, \quad \mathbf{B} = \langle x₂, y₂, z₂ \rangle$$A=⟨x1​,y1​,z1​⟩,B=⟨x2​,y2​,z2​⟩

Then the cross product is:$$\mathbf{A} \times \mathbf{B} = \langle (y₁z₂ – z₁y₂), -(x₁z₂ – z₁x₂), (x₁y₂ – y₁x₂) \rangle$$A×B=⟨(y1​z2​−z1​y2​),−(x1​z2​−z1​x2​),(x1​y2​−y1​x2​)⟩

Magnitude:$$|\mathbf{A} \times \mathbf{B}| = \sqrt{(y₁z₂ – z₁y₂)^2 + (-(x₁z₂ – z₁x₂))^2 + (x₁y₂ – y₁x₂)^2}$$∣A×B∣=(y1​z2​−z1​y2​)2+(−(x1​z2​−z1​x2​))2+(x1​y2​−y1​x2​)2​

Direction follows the right-hand rule.

This logic ensures accurate vector results.
