Diff EQ: Phase Portrait Analysis

Hello!

I am lecturing (read blabbing) about how to perform a phase portrait analysis on a non linear DE. The point of this lecture is to teach an alternative way to show what the general family of functions of the DE in question would look like in a slope field format without actually solving the DE analytically. This method is a useful tool to quickly gauge the behavior of a function (graphically) and determine the results’ relevance to the situation called for.

Differential Equations tutorial: Separation of Variables Technique

Below is my inaugural attempt at pencasting using my livescribe smart pen. I have recently finished the aforementioned mathematics course in which I have used this pen for all lecture notes from the class. The pen is simply amazing as a tool to maintain both the lecture and written notes in sync with each other (which can be very helpful in academic or business settings).  I hope those who are in need of this lecture find it useful if not fully enlightening,  and for those who are interested in a review about the pen, I may prepare a review of my experience with it soon.

Sadly I recently found out that WordPress will not support pencast files (not cool) so please forgive the added inconvenience of having to click a link.
