And so obviously, when ... WebCross Product. For example, if we have two vectors in the X-Y plane, their cross product will result in a resultant vector in the direction of the Z-axis, which is perpendicular to the XY plane. Between the original vectors, the symbol is used. The k product, often known as the cross product of two vectors, looks like this: Formula
