Our general solution to the ode (4.4.1) when b2 − 4ac = 0 can therefore be written in the for x(t) = (c1 + c2t)ert, where r is the repeated root of the characteristic equation. The main result to be remembered is that for the case of repeated roots, the second solution is t times the first solution.These are two distinct real solutions to the system. In general, if the complex eigenvalue is a + bi, to get the real solutions to the system, we write the corresponding complex eigenvector v in terms of its real and imaginary part: v = v 1 + i v 2, where v 1, v 2 are real vectors; (study carefully in the example above how this is done in ...

eigenvector, ∂1, and the general solution is x = e 1t(c1∂1 +c2(t∂1 +λ)), where λ is a vector such that (A− 1I)λ = ∂1. (Such a vector λ always exists in this situation, and is unique up to addition of a multiple of ∂1.) The second caveat is that the eigenvalues may be non-real. They will then form a complex conjugate pair. It is therefore possible that some or all of the eigenvalues can be complex numbers. To gain an understanding of what a complex valued eigenvalue means, we extend the domain and codomain of ~x7!A~xfrom Rn to Cn.
