In mathematics an vector algebra, the cross product or vector product (occasionally directed area product tae emphasize the geometric signeeficance) is a binary operation on twa vectors in three-dimensional space (R3) an is denotit bi the seembol ×. Given twa linearly independent vectors a an b, the cross product, a × b, is a vector that is perpendicular tae baith a an b an tharefore normal tae the plane conteenin them. It haes mony applications in mathematics, pheesics, ingineerin, an computer programmin. It shoud nae be confused wi dot product (projection product).
