While practicing computations in MATLAB, you find a 3 x 3 matrix A and vectors v, w with Av = v, Aw = w and v x w + 0. Determine if A could represent: • a projection on a line, • a projection on a plane, • a reflection across a line, • a reflection across a plane, or • a rotation. Justify your answer by providing an example of a matrix and vectors, or a reason why they can't exist.
