I've got a homework problem that I am needing to do; however, I am not sure really what the question is asking. Obviously since I don't know what is being asked, I don't know where to begin.(adsbygoogle = window.adsbygoogle || []).push({});

I was hoping for some insight.

Question:

Show that matrix

A = {cos (theta) sin (theta), -sin (theta) cos (theta)}

will have complex eigenvalues if theta is not a multiple of pi. Give a geometric interpretation of this result.

Can anyone clear this up for me or help?
