Homework Zero (No due date)
 Section 1.3: 17, 11, 15, 17, 19
Reading: Chapter 1 Sections 1  3. We will not discuss these sections in class, but they introduce several key ideas that we will revisit throughout the course. 

Homework 1 (Due Fri, Oct 4)
 Section 2.1: 1c, 3c, 4c, 6c, 14, 15, 20, 31
 Section 2.2: 1, 2, 3, 4, 6, 9a, 17a, 19a, [30(abcde), 32b]
 Section 2.3: 13, 15, 17a, 18a
 Section 2.4: 1, 5, 14, 15, [27, 28]
Reading: Chapter 2, Sections 14. We will not spend much time in class discussing 2.3 (Modeling with First Order Equations), but this section gives valuable insight into why exactly we want to study differential equations and find their solutions. 

Homework 2 (Due Fri, Oct 11)
 Section 2.5: 3, 12, 13, [16, 22, 23]
 Section 2.6: 1, 3, 6, 8, 10, 15, [20, 22]
 Section 3.1: 1, 2, 3, 9, 16, 18, 20, 23
Reading: Chapter 2, Sections 5 and 6. You can skip "Integrating Factors" (pages 99100) in Section 2.6. Also read Chapter 3, Section 1. 

Homework 3 (Due Fri, Oct 18)
 Section 3.2: 1, 2, 3, 7, 9, 13, 14, 24
 Section 3.3: 8, 9, 15, 19, 21, 22, 27, 29, [34, 36]
 Section 3.4: 1, 2, 8, 11, 12, 14, 23, 25
Reading: Chapter 3, Sections 24. 

Homework 4 (Due Fri, Oct 25)
 Section 3.5: 1, 6, 8, 9, 16, 17
 Section 3.6: 7, 10, 13, 17
Reading: Chapter 3, Sections 5 and 6. Pay special attention to Table 3.5.1 on page 182. We may not have time to deal with each case in class. In 3.6, the emphasis is on learning to correctly use the formulas in Theorem 3.6.1. 

Homework 5 (Due Fri, Nov 1)
 Section 7.1: 1, 5, 7, 11, 12, [13]
 Section 7.2: 2, 10, 22, 23
Reading: Chapter 7, Sections 1 and 2. We will restrict our discussion of matrices to the 2x2 case, so whenever the book makes general statements in Chapter 7, you can always think of them in terms of 2x2 matrices. 

Homework 6 (Due Fri, Nov 8)
 Section 7.3: 13, 14, 16, 17, 18, 21
 Section 7.4: 4, 6, 7
 Section 7.5: 1a, 2a, 3a, 15, 16, [24, 27]
 Section 7.6: 1a, 3a, 9, 10, 13(ab), [26, 28(ab)]
Reading: Chapter 7, Sections 3  6. We will not explicitly discuss 7.3, but we will cover the material as part of the 7.2 and 7.4 lectures. As before, we will consider only 2x2 systems. 

Homework 7 (Due Fri, Nov 15)
 Section 7.8: 1c, 2, 7, 10, [16]
 Section 7.9: 1, 3, 7, 9
Reading: Chapter 7, Sections 8  9. (You can skip Section 7). As before, we will consider only 2x2 systems.

 Section 5.2: 1, 6, 7, 9, [21]
Reading: Chapter 5, Sections 1  2. 

Homework 9 (Due Fri, Dec 6)
 Section 6.1: 3, 5, 12, 15, 21, 23
 Section 6.2: 1, 2, 7, 11, 16, 23
 Section 6.3: 1, 4, 10, 14, 16
Reading: Chapter 6, Sections 1  3. 

Homework 10 (No due date)
 Section 6.4: 1, 2, 3, 5, 11
