Complex eigenvalues general solution
What if we have complex eigenvalues? Assume that the eigenvalues of Aare complex: λ 1 = α+ βi,λ 2 = α−βi (with β̸= 0). How do we find solutions? Find an eigenvector ⃗u 1 for λ 1 = α+ βi, by solving (A−λ 1I)⃗x= 0. The eigenvectors will also be complex vectors. eλ 1t⃗u 1 is a complex solution of the system. eλ 1t⃗u 1 ...

To find an eigenvector corresponding to an eigenvalue , λ, we write. ( A − λ I) v → = 0 →, 🔗. and solve for a nontrivial (nonzero) vector . v →. If λ is an eigenvalue, there will be at least one free variable, and so for each distinct eigenvalue , λ, we can always find an eigenvector. 🔗.Complex eigenvalues: l = p+iq, l = p iq (q 6= 0) If the eigenvector v = p +iq correspoinds to l, then v = p iq is the eignevector ofl. The general solution is x(t) = c1<(eltv)+ c2=(eltv). Applying Euler’s formula and some trigono-metric identities we may write the general solution as x(t) = Cept sin(qt g)p +cos(qt g)q where C and g are ...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.

One that is particularly easy to solve is y0= ay: It has the solution y= ceat, where cis any real (or complex) number. Viewed in terms of linear transformations, y= ceat is the solution to the vector equation T(y ...equation (1), and its integral curves give a picture of the solutions to (1). Two integral curves (in solid lines) have been drawn for the equation y′ = x− y. In general, by sketching in a few integral curves, one can often get some feeling for the behavior of the solutions. The problems will illustrate. Even when the equation can be solved ...
