Dual space. Let V be a finite dimensional vector space over a field F.

The dual space of V , denote V* , is defined to be the space

V* = Hom(V, F) = {φ : V → F; φ is linear transformationg},

of all linear transformations from V to F. The elements of V* are, sometime, called functionals.

(a) Show that dim(V ) = dim(V* ).

(b) Suppose now that F = R, and V is an inner product space, with inner product ( , ). Consider the natural mapping
