2. Let u-("і "2,W3), ν(η , v 2, vs), and w-( w. w2,W3 ) be three vectors in R. Recall thatthe oriented volume V(u,v,w) of the parallelepiped spanned by u,v,w equals (их v) . w(See p. 45 for the definition of the cross product.)(b) If A is a 3 x 3-matrix, prove thatV(Au,Av,Aw)-det(A)V(u, v, w).Remark. The formula from (b) shows that det(A) measures how the linear transformation with matrix A changes the volume of a region in R5.
