The set of vectors S = {v1, v2, v3}, where v1 = (1, 0, 1), v2 = (-1, 4, 1), v3 = (2, 1, -2), forms an orthogonal basis with respect to the standard inner product on R^3. Express the vector u = (8, -4, -3) as a linear combination of v1, v2, and v3. Also, find the coordinate vector relative to this basis.
