# Cross Product of 3D Vectors

 The cross (or vector) product of two vectors $$\vec{u} = (u_x , u_y ,u_z)$$ and $$\vec{v} = (v_x , v_y , v_z)$$ is a vector quantity defined by: The cross product $$\vec{u} \times \vec{v}$$ is perpendicular to both $$\vec{v}$$ and $$\vec{u}$$ The right hand rule, to find the direction of the cross product, is as follows: point the index in the direction of $$\vec {u}$$, the middle finger in the direction of $$\vec{v}$$ and the direction of the cross product $$\vec {u} \times \vec {v}$$ is in the same direction as that of the thumb.
