Question Number 18094 by Tinkutara last updated on 15/Jul/17

\vec{A}, \vec{B} and \vec{C} are three non - collinear,

non co - planar vectors . What can you

say about direction of \vec{A} \times (\vec{B} \times \vec{C}) ?

\vec{A} \times (\vec{B} \times \vec{C}) is the cross product of

the component of \vec{A} in the plane

of \vec{B} and \vec{C} with \vec{B} \times \vec{C} .

It is parallel to the plane of \vec{B} and \vec{C} .
