Continuing with youContinuing with your weekly conversations with your engineering friend, the one who knows Calculus I and II, and who knows what you have been doing up to now in your ODEs course, how would you explain to them, in your own words, the following concepts in a few short sentences: (1) the system is almost linear (locally linear) at a point in the phase plane, (2) phase portrait, (3) a basin of attraction, and (4) a separatrix.r weekly conversations with your engineering friend, the one who knows Calculus I and II, and who knows what you have been doing up to now in your ODEs course, how would you explain to them, in your own words, the following concepts in a few short sentences: (1) the system is almost linear (locally linear) at a point in the phase plane, (2) phase portrait, (3) a basin of attraction, and (4) a separatrix. Exercise 2. (On the meaning of Figure 9.1.0 on page 507 in the text) Given the system x = Ax = [ a b c d ] x, let p = tr(A) = a d, and let q = det(A) = ad bc, and finally let
