Calculus of One and Several Variables

14.5 Proof of the distributive law

Let x be a vector. From the above observation,

x ⋅ a×
 =
⋅
=
⋅ b+
⋅ c
= x ⋅ a × b + x ⋅ a × c = x⋅
.

Therefore,

for all x. In particular, this holds for x = a×

−
showing that a×
= a × b + a × c and this proves the distributive law for the cross product.

Observation 14.5.1 Suppose you have three vectors, u =

,v =
, and w =
. Then u ⋅ v × w is given by the following.

The message is that to take the box product, you can simply take the determinant of the matrix which results by letting the rows be the rectangular components of the given vectors in the order in which they occur in the box product.
