The Cross Product Many applications in physics, engineering, and geometry involve finding a vector in space that is orthogonal to two given vectors. In this section, you will study a product that will yield such a vector. It is called the cross product, and it is conveniently defined and calculated using the standard unit vector form.

It is important to note that this definition applies only to three-dimensional vectors. The cross product is not defined for two-dimensional vectors. A convenient way to calculate is to use the following determinant form with cofactor expansion. (This determinant form is used simply to help remember the formula for the cross product—it is technically not a determinant because the entries of the corresponding matrix are not all real numbers.) The Cramer's rule

Both and are perpendicular to the plane determined by u and v. One way to remember the orientations of the vectors u,v , and is to compare them with the unit vectors i , j. The three vectors u, v, and form a right-handed system.
