*********************************************************
Tentative list of Homework Problems
(those in parenthesis are required of graduate students only)
*********************************************************
GL Chapter 1:ZT Chapter 1:
(1.1),1.2, (1.3), 1.4
For problem 1.2: To show 2 sets are equal (A=B), show A is contained in B and B is contained in A.
2.1, 2.4, 2.5, (2.6)
3.1, 3.2, (3.3), 3.4, 3.6 b,c
For 3.1: reason this result geometrically only. For 3.2: Use 3.1
4.1, 4.2, 4.3, 4.4a, 4.5, 4.6
For 4.1 may use Leibniz Thm,. For 4.2 use the error function.
ZT Chapter 3:
(1.1), 1.2
2.1a, (2.1c), 2.1e, 2.1g; 2.4
Problem 2.1: Be sure to define domains carefully. 2.1a is quite involved, you may want to do this after you have done some other problems. 2.1c For 2nd integral, use a trick of adding/subtracting. 2.1e: See Ch 2 example 2.3 – you do not have to derive u_1 or u_2, but you need to verify that the two are functionally independent first integrals. 2.1g: See Ch 2, example 2.4 – you do not have to derive u_1 - find u_2 and verify that the two are functionally independent first integrals.
3.1a,b,c,d,g;
Be sure to check determinant condition to guarantee solution exists and is unique (and mentally check that coefficients and initial curve are smooth enough); For 3.1c use results from 2.1g;
3.3, (3.4)
4.1b
what happens if you try to solve it (choose one method and try to solve it).
ZT Chapter 3:5.1, 5.2, 5.3, (5.4), 5.5, (5.6), (5.8 [for 5.6 only])
6.1, 6.6, 6.9
GL Chapter 2:
Section 2.1:
(2), 3 [graph at t=0, t=1, t=2], 4, (6 [parametrize initial curve in 2 parts])
Section 2.5: 2
ZT Chapter 4:
(1.1), 1.2a,b ; 1.3, 1.5a
(2.1a,c); (2.2)
ZT Chapter 5:
1.1
(2.1a,c); (2.2b); 2.3
ZT Chapter 5:
3.1 [
For problem 3.1: Try to solve the IVP and find a global solution,
i.e. a solution which works everywhere. Show that phi(x)
must
be
an even function (this is the 'certain condition') in order for a
global solution to exist. What happens if phi(x) is not an
even
function? (Where do solutions exist?). What is the
point of this problem?]
(4.2), 4.4
6.1, 6.2a,b
7.5, 7.7
9.1, 9.2a, (9.2b), (9.3)
ZT Chapter 6:
1.1, 1.2, 1.3, 1.4
(2.1), 2.2, 2.3
(4.1a), 4.1b [for 4.1b you’ll need Liebniz’ Rule]
5.3 [This is another example of an ill-posed (not well-posed) problem. Take a moment and note that the data does not make physical sense].
ZT Chapter 7:
1.1, 1.2a, (1.2b), 1.3
For 1.2b: see p. 59, number 1.1. For 1.3: patience.
2.3, 2.4, 2.5, 2.7
For 2.7b, you want to integrate lambda from 0 to + infty.
(5.2) [for 5 points extra credit, do not have to do], (5.4), (5.6)
Hint on 5.6: start with MVP, replace delta by r and integrate both sides from 0 to delta with respect to r;
(7.2), (7.3), 7.4, 7.6, 7.7a,b,c
For 7.4: Series solution is valid only for r<a, so one must integrate first and then take limits. For 7.7: Take advantage of whether function is even or odd
8.1, 8.2, 8.3, 8.4, (8.5), 8.6, 8.7, 8.9, 8.10a,b,c, (8.14)
For 8.1: patience. For 8.4: Do not calculate, use the fact that the integral of an odd function about an interval symmetric with respect to the origin is zero. Do not worry about convergence
(9.3a,b), (9.4)
(10.1), (10.2), (10.3)
11.1
12.3, 12.4, 12.7

1.1, 1.2, 1.3, 1.4, 1.5, 1.6
