Question

Vector product under rotation​

Answer 1

Answer:

The only vectors that won't change at all under a rotation of the u-v plane are those vectors that are perpendicular to the plane. Hence, the cross product of two vectors u and v must give a new vector which is perpendicular to both u and v.

Answer 2

Answer:

The only vectors that won't change at all under a rotation of the u-v plane are those vectors that are perpendicular to the plane. Hence, the cross product of two vectors u and v must give a new vector which is perpendicular to both u and v.
