Problem 3.3. For the following vector spaces V and maps : V → V prove that they are linear, and write their matrices in the indicated basis of V a) o : R³ → R³, 6(x, y, z) = (3x − y + 2z, -x-y+z, -2x + y - 4z); standard basis of R³. b) basis of R3 : R³ R³, is the rotation with respect to the x-axis by 60 degrees counterclockwise; standard c) V is the space of all polynomials of degree at most n, o(P(x)) = P'(x)+2P(x); basis (1, x,,,,).
