MAT211 Review for Midterm 2 Coordinates - Linear spaces - Orthogonality 1 Example (4.1-25) Let W be the space of all polynomials f in P 3 such that f(1)=0. Determine whether the following subspace of P 3 and if so, Fnd its dimension. EXAMPLE (4.2-13) Let T be a transformation from R 2x2 to R 2x2 deFned by T(M)=A.M - M.A where A is the matrix ±ind out whether T is linear. If it is, Fnd kernel, image and nullity and determine whether is an isomorphism. 1 2 0 1 EXAMPLE (4.2-67) ±or which constants k is the linear transformation T(M)=AM-MB an isomorphism if A and B are the matrices 2 3 0 4 3 0 0 k EXAMPLE (4.3-21) ±ind the matrix (with respect to the standard basis) of the transformation T
