Dot product and cross product as linear transformations

Let R3 denote the 3-dimensional vector space, and let v=(a,b,c) be a fixed nonzero vector. The maps C:R3R3 and D:R3R defined by C(w)=v×w and D(w)=(vw)v are linear transformations.

  1. Determine the eigenvalues of C and D.
  2. Determine the eigenspaces of C and D as subspaces of R3, in terms of a,b,c.
  3. Find a matrix for C with respect to the standard basis.

Show all work and explain reasoning.
