(i) Combine Exercises 10.1.23–24 to show that if A = SS⁻¹ is diagonalizable, then the solution to u̇ = Au can be written as u(t) = S (c₁ e^{λ1 t}, . . . , c_n e^{λn t})T, where λ₁, . . . , λ_n are its eigenvalues and S = (v₁ v₂ . . . v_n) is the corresponding matrix of eigenvectors.

Prove that the general solution to a linear system u̇ = Λu with diagonal coefficient a matrix Λ = diag (λ₁, . . . , λ_n) is given by u(t) = (c₁ e^λ1 t, . . . , c_n e^λnt)^T.
