Document Summary
Show your work, and justify all your answers. Partial credit will be given for solutions on the right track that might not be complete. Therefore it is recommended that you attempt all prob- lems: [20 points] consider the following matrix a and vector b: If so, express b as a linear combination of the basis vectors you found in part (c): [10 points] let w = span{ . 1 (a) find the eigenvalues and eigenvectors of a. (b) find an orthogonal matrix p such that d = ptap is diagonal. What is d? (c) determine a formula for ak, k n: [20 points] de ne the linear transformation t : r2[x] m22 by c] , Justify your answers. (d) find the matrix representation of t with respect to the bases b = {1, 1 + x, 1 + x + x2} of. 0 1]} of m22: [15 points] let t be the following transformation,
