## Homework Statement

Let[tex]v_1,v_2,...v_n[/tex] be a basis of V and let [tex]w_1,w_2,...w_n[/tex] be any n elements in V. Define T on V by

[tex](\lambda_1 v_1+\lambda_2 v_1+...+\lambda_n v_n)T=\lambda_1w_1+....\lambda_n w_n.[/tex]

a)Show that R is a homomorphism of V into itself.

b)When is T an isomorphism?

## Homework Equations

An isomorphism is a 1-1 mapping.

## The Attempt at a Solution

I think I have part a) done, although It makes more sense to me to prove that T is a Hom, not R...not sure where the R came from.

For part b, I am thinking that since the [tex]v_i[/tex] are a basis that the Iso would be true if the w's were a basis also?

IK know that an iso occurs when the Kernel is zero..but I'm still kinda confused here.

Any hints or advice will be appreciated.

Thanks,
