Answer 2

Let {a,b,c} be a given linear independent set of vectors. Suppose that vectors l,m,n are such that r=(l.r)a+(m.r)b+(n.r)c for all vectors r. Prove each of the following :
(i)l.a=m.b=n.c and l.b=l.c=m.a=m.c=n.a=n.b=0,
(ii)The set of vectors {l,m,n} is linearly independent.
(iii)l=(bxc)/(a.bxc), m=(cxa)/(a.bxc), n=(axb)/(a.bxc).
