Title: Phase Portrait Questions
Post by: Nicholas Zomparelli on November 18, 2014, 09:32:07 AM
Hello,

I have a few questions about phase portraits and what we'll have to know about them for our Term Test #2

1) So far in lectures, we've leaned how to draw phase portraits of 2x2 systems of linear equations. Will we have to know how to draw phase portraits for 3x3 systems for this test?

2) Also I'm curious about phase portraits for nonhomogeneous systems. We haven't talked about this either in lecture, but is there a possibility that something like this could be on the test?

Thank You,

-Nick

No.

We do not put in the tests what was not covered (and in fact neither is covered even in textbook)
