Equate the area of a parallelogram with the magnitude. The 11th installment in a 15-video series introduces the concept of the cross product of two vectors. The presentation makes the geometric connection between the cross product, the determinant, and the area of the parallelogram defined by the vectors. The video describes the orientation of the cross product by using the right-hand rule.
