Prove that

u x (v x w) = (u*w)v - (u*v)w

2. Relevant equations

I've been trying to get this one but keep ending up no where.

I've tried the normal algebraic properties of the cross product but they lead me to a dead end.

What im trying right now is just proving it in three space. Assigning each vector to a general form like (u1, u2, u3) and busting it out to see if I can get the right side identity.

Is there an easyier way to start this out.

Ideas are much appreciated.

Rob
