First day handout

Table of Laplace transforms; these formulas will be given to you on the second midterm test,
so feel free to use them for HW problems:

Solutions to some HW problems:

5.2: 3a pdf

Most from 6.1 and 6.2
pdf

Homework problems:

HW1, due Thursday:

1.1: 1, 19;

1.2: none;

1.3: 1, 4, 7;

Since some of you may not have obtainted the textbook yet, here are scans of
the problems:
page 1,
page 2,
page 3.

HW2, due Thursday:

2.1: 1(c), 4(c), 12.

2.2: 5, 13(a);

HW3, due Thursday:

2.6: 1, 5, 9;

Miscellaneous problems (at the end of Chapter 2): 1, 2, 3.

2.3: 1.

2.4: 1, 5, 11;

3.1: 1, 8, 11 (no need to graph the solution, but do describe the behavior as t increases);

HW4, due Tuesday:

3.2: 1, 19;

3.3: 12, 13, 15 (no need to graph the solution, but do describe the behavior as t increases);

HW5, due Thursday during the test or by Friday 1pm in my mailbox:

3.4: 9, 11, 18 or 19 (again, no need to graph the solution, but do describe the behavior as t increases;
also 19 is a better problem than 18, if you have not tried 18 already).

HW6, due Thursday:

3.5: 4, 5, 11, 17(a);

3.6: 1, 7, 10;

HW7, due Thursday:

5.2: 1a, 1b, 3a, 3b;

HW8, due Tuesday:

6.1: 4a, 17.

6.2: 9 (you only need formula 2 from table 6.2.1 in the book, which is the same as in example 5 in section 6.1).

HW9, due Tuesday:

6.2: 12, 14, 16.

HW10, due Thursday:

5.2: 4a, 4b.

HW11, due Tuesday:

6.3: 1, 2, 8, 10, 14;

HW12, due Thursday:

6.4: 1b, 6b.

6.5: 1a.

6.6: 12.

HW13, due Thursday:

4.1: 2, 9.

4.2: 20, 22 (for both, no need to graph or discuss behavior at infinity).

4.3: 1, but find only a particular solution (not the general solution).

Some practise problems for the final (NOT practise final, not to be turned in)
