The cross product is a mathematical operation used in vector algebra. It takes two vectors, often represented in three-dimensional space, and produces a third vector that is perpendicular to both of the original vectors. The magnitude of this resulting vector is determined by the area of the parallelogram formed by the two input vectors. To calculate the cross product, you can use the formula involving the sine of the angle between the vectors and their magnitudes. The cross product is commonly denoted as A × B, where A and B are the original vectors. This operation is widely used in physics and engineering, particularly in calculating torque and angular momentum.
