Unformatted text preview: MATH 310 Fall 2011 Differential Equations Homework Exercises, Set 10 Quiz on Wednesday, 30 November 2011 Course Information is on WebCT . The quiz will be based on the problems from Section 7.1 (converting between higherorder equations and firstorder systems; nullclines and phase portraits) and Section 7.5 (linear constant coefficient systems with real eigenvalues). Textbook references are to: Boyce and DiPrima Elementary Differential Equations and Boundary Value Problems (9th edition). Reading : Sections 7.1, (7.2, 7.3), 7.4, 7.5, 7.6 Problems to prepare for quiz (no need to hand in): Section 7.1, # 3, 6, 10, 12 Firstorder equations, method of elimination, phase portraits For #10 & 12 , also plot fixed point(s) and nullclines in the phase diagrams, and use them to determine the regions where x or y are increasing/decreasing; hence sketch the phase portrait see the lecture notes pp.7.87.11 ....
