These notes are from Prof. Chua's book titled "Linear and Nonlinear Circuits" (co-authors: Kuh and Desoer). The book is out of print, so we are posting relevant pages from the book on this website.
You should read the class textbook and study these notes for understanding the course material. The reason we follow this approach instead of teaching you just circuits is: you are not EE majors. You probably will never analyze a circuit outside of this class. So, we adopt a mathematical approach to circuits so you can apply the mathematical knowledge to your major. You will **hopefully** understand what I am talking about as the class progresses.
