Cross product of two vectors, showing the perpendicular result and parallelogram area
This program displays two vectors in R3 and their cross product, showing how the resulting vector is perpendicular to both inputs with magnitude equal to the area of the parallelogram they span. The cross product is fundamental in multivariable calculus and physics, appearing in torque, angular momentum, and the computation of surface normals.
