Monday october 19, 5:00- 5:50pm october 16, 2015. Consider the 4 4 matrix a and vector b r4 given by. Let s : r3 r3 be a linear map such that. 0 (b) find a matrix b such that for any vector x r3 we have bx = sx (hint: compute s(e1), s(e2), s(e3)). Explain your answers. (a) the map t : r2 r2, (x, y) (cid:55) (x2, x + y) is linear. (b) the vectors. R4. span r4. (c) let v1, v2, v3, v4 r4.
