How the Cross Product Calculator Works

The calculator uses the standard mathematical formula for the cross product of two vectors A and B:$$\mathbf{A} \times \mathbf{B} = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ A_x & A_y & A_z \\ B_x & B_y & B_z \end{vmatrix}$$A×B=​iAx​Bx​​jAy​By​​kAz​Bz​​​

Steps to use the tool:

1. Input Vector Components: Enter the x, y, and z components of Vector A and Vector B.
2. Click Calculate: The calculator computes the resulting vector using the determinant formula.
3. View Results: The output shows the cross product vector in component form and optionally as a magnitude.

This eliminates manual determinant calculations and ensures accurate, professional results.

Practical Examples

Example 1: Basic 3D Vectors

• Vector A: (2, 3, 4)
• Vector B: (1, 0, -1)
• Calculation:

$$A \times B = (3×-1 – 4×0, 4×1 – 2×-1, 2×0 – 3×1) = (-3, 6, -3)$$A×B=(3×−1−4×0,4×1−2×−1,2×0−3×1)=(−3,6,−3)

Example 2: Perpendicular Vectors

• Vector A: (1, 0, 0)
• Vector B: (0, 1, 0)
• Calculation:

$$A \times B = (0, 0, 1)$$A×B=(0,0,1)

Example 3: Magnitude of Cross Product

• Vector A: (3, -3, 1)
• Vector B: (4, 9, 2)
• Calculation:

$$|A \times B| = \sqrt{(-15)^2 + (-2)^2 + (39)^2} ≈ 42.84$$∣A×B∣=(−15)2+(−2)2+(39)2​≈42.84

Using the Cross Product Calculator ensures these calculations are fast, accurate, and reliable.
