21260 Differential Equations
Assignments: Week #8
 Reading:
 Monday: Sections 3.4 and 3.5. (Note that we are taking a different approach
to these problems, utilizing our knowlege of linear systems.)
 Wednesday: Section 3.8.
 Friday: MidSemester Break.

 Exercises: Due on Thursday 9 March.
 Section 7.1 #1, 5.
 Section 3.1 #4, 16, 19.
 Section 3.4 #12, 18, 23.
 Section 3.5 #4, 14.
 Notes:
 In 7.1.5, replace 2cos(3t) with
0, to make a homogeneous equation.
 Solve problem 3.1.4 by explicitly
converting it to a system of first order differential equations. The others
can be solved using formulas derived in class  see equation 3.1.17.
 Solve problem 3.4.12 by explicitly
converting it to a system of first order differential equations. The others
can be solved using formulas derived in class  see equation 3.4.17.
 Solve problem 3.5.4 by explicitly
converting it to a system of first order differential equations. The others
can be solved using formulas derived in class  see equation 3.5.26.
