A vector cross product is the product of two vectors that yields another vector. This product vector points in the direction perpendicular to the plane spanned by the other two vectors. There are many applications of the cross product, including torque a
Let’s represent the rotation matrix R in terms of its row vectors: From this, we get Ra and Rb as the following: By the analytical definition of the cross product, we have It can be then shown that the following identity is true for vectors A, B, C and D : Allowing for Now, fo...

What the definition tells us is that the vector cross product of any two vectors is a third vector that is perpendicular to both of them (and to the plane that contains them). This is possible in 3-dimensional space because, in such space, there are three independent directions. You can...

The cross product a× b is defined as a vector c that is perpendicular to both a and b, with a direction given by the right-hand rule and a magnitude equal to the area of the parallelogram that the vectors span. The cross product is defined by the formula[3][4] {\displaystyle \mat...
