How the Cross Product Calculator Works

The cross product of two vectors A and B in 3D is denoted as A × B and results in a vector that is perpendicular to both A and B. It is calculated using the determinant of a matrix: A×B=∣ijkAxAyAzBxByBz∣\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​​​

Where Ax,Ay,AzA_x, A_y, A_zAx​,Ay​,Az​ and Bx,By,BzB_x, B_y, B_zBx​,By​,Bz​ are the components of vectors A and B along the x, y, and z axes. The resulting vector points perpendicular to the plane formed by the original vectors, following the right-hand rule.

Practical Example

Suppose we have two vectors: A=(2,3,4),B=(5,6,7)\mathbf{A} = (2, 3, 4), \quad \mathbf{B} = (5, 6, 7)A=(2,3,4),B=(5,6,7)

Using the formula: A×B=∣ijk234567∣\mathbf{A} \times \mathbf{B} = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ 2 & 3 & 4 \\ 5 & 6 & 7 \end{vmatrix}A×B=​i25​j36​k47​​

The result is: A×B=(−3,6,−3)\mathbf{A} \times \mathbf{B} = (-3, 6, -3)A×B=(−3,6,−3)

The calculator provides this instantly without any manual determinant calculations, saving time and reducing errors.
