Problem 1
1) Find the Jordan form of the following matrix A, and give the corresponding transformation matrix P.
A = 1 1 1(2) (1)
[ 0 0 −3
2) Compute the solution of the differential equation ˙(x)(t) = Ax(t) with the initial condition x(0) = [0, 2, 1]T .
Problem 2
Let x ∈ Rn , a ∈ R, and A ∈ Rn ×n be a real symmetric positive semidefinite matrix. Let B = [xT(A) a(x)].
Prove that if B ⪰ 0 (positive semidefinite), then, x ∈ Range(A), noting that Range(A) = {y ∈ Rn : y = Ac for c ∈ Rn } .
