Justify statement 1-4 and explain why.
If a matrix A is invertible, then all the eigenvalues of A are nonzero. If two linear maps have the same characteristic polynomial, then they always have the same Jordan canonical form. If a linear map from the vector space P of all polynomials to itself is injective, then it is an isomorphism. If W, and W2 are subspaces of a vector space V, then the projection T: W W 2 → W, i.e.,...

3. In the following question, we are going to prove that ker(T) = { } if and only if T is one-to- one. (Writing prove is like writing a little essay, with some good logical connection between each sentence.) (a) Let T:V - W a linear transformation between two vector spaces. Suppose ker(T)={0}. Show that T is one-to-one. (Hint: proof by contradiction, by assuming both ker(T)=ð and T is not one-to-one. Now, apply definition of kernel and one-to-one, what is...
