The Skeleton Key of Mathematics - A Simple Account of Complex Algebraic From Particle Systems to Partial Differential Equations - Particle Systems and The solution that we get from the first eigenvalue and eigenvector is, → x 1 ( t) = e 3 √ 3 i t ( 3 − 1 + √ 3 i) x → 1 ( t) = e 3 3 i t ( 3 − 1 + 3 i) So, as we can see there are complex numbers in both the exponential and vector that we will need to get rid of in order to use this as a 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 practice). Then is a homogeneous linear system of differential equations, and $r$ is an eigenvalue with eigenvector z, then \[ \textbf{x}=\textbf{z}e^{rt} \] is a solution.

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 practice). Then is a homogeneous linear system of differential equations, and $r$ is an eigenvalue with eigenvector z, then \[ \textbf{x}=\textbf{z}e^{rt} \] is a solution. (Note that x and z are vectors.) In this discussion we will consider the case where $r$ is a complex number \[r = l + mi.\] The equation translates into Since , then the two equations are the same (which should have been expected, do you see why?). Hence we have which implies that an eigenvector is We leave it to the reader to show that for the eigenvalue , the eigenvector is Let us go back to the system with complex eigenvalues . Note that if V, where By definition the exponential of a complex number z = a + bi is ea + bi = ea (cosb + isinb). Replacing b by − b, and using that cos( − b) = cosb, sin( − b) = − sinb , leads to ea − bi = ea (cosb − isinb).
