Using them, trigonometric functions can often be omitted from the methods even when they arise in a given problem or its solution.By Euler's formula, if we restrict our solutions to be real we get the familiar periodic sine and cosine. In general the eigenspaces will not be one-dimensional and then the theory of Jordan normal form applies. This occurs, for example, when finding the general form of damped harmonic motion.However if the eigenvalues are complex, it is less obvious how to find the real solutions. Because we are interested in a real solution, we need a strategy to untangle this. We examine the case where A has complex eigenvalues λ1 = λ and λ2 = ¯λ with corresponding complex eigenvectors W1 = W and W2 = W .These solutions are linearly independent if n = 2. If n > 2, that portion of the general solution corresonding to the eigenvalues a±bi will be c1x1 +c2x2. Note that, as for second-order ODE’s, the complex conjugate eigenvalue a−bi gives up to sign the same two solutions x1 and x2. We therefore take w1 = 0 w 1 = 0 and obtain. w = ( 0 −1) w = ( 0 − 1) as before. The phase portrait for this ode is shown in Fig. 10.3. The dark line is the single eigenvector v v of the matrix A A.
