Final Exam tomorrow. See below.
Be sure to bring your integration sheet, undetermined coefficient sheet
and Laplace transform sheet with you to class. (Bring yourself also
along with a pencil. HaHA) Bring a stamped self-addressed envelope
if you want a final copy of EMB. |
| 7/9=W |
HW: P: 352/7-12, 24-34 (Turn
in last project.) If you get the chance look over the Maple worksheets
on Laplace. Read: Chapter 14 Final Exam: Start stidying by going over previous test, then move to back homeworks. Go through each chapter 1 -10, 13,14 making sure you understand the boxed ideas.(Don't forget Chapter 3: Direction Fields and Chapter 4: Euler's method). Chapter 5 stops at Gronwall's Inequality p.107. Chapter 6 stops at Radioactive Decay p. 121. Chapter 7 stops at Abrupt Change Property p 155. Chapter 8 stops at Integra curves p. 180. Chapter 9 stops at Cauchy-Euler Equations p. 204. Good luck. |

HW: Using the definition
of Laplace transform work out 1.) ₤{t²} and ₤{e^(4t)} P:
352/1,4 Read: Carefully read the section on Exponential Order starting on p 334 Test: Test 4 is due at the beginning of class Wednesday. Last "Project": Write out all of the steps in the proof of ₤{f(t)u(t-b)} = e^(-bs)₤{f(t+b)} starting in the middle of p. 346. Due: Thursday Maple Worksheets: for Laplace transforms and solving DE's with then are now available under Maple Worksheets |
| 7/7=M |
HW: C: 237/16,20,22 (Note
Don't attempt 17 & 19.) You should try 23 & 24c but they
are not assigned. HW Ans in Word Read: Chapter 13 expecially where Dr. Becker shows how the Laplace Transform was developed on pp. 319-23. Test: The test should be worked using the method of undetermined coefficients where applicable and note 5b should read "... find L[y1](x)" not L[y1(x)](x) |
| 7/3=R |
HW: C:209
/(2,8,19 from yesterday),5,10,24; 236/5,7,13; HW Answers in Word
P: 209/1-24 even (don't forget typo on #24: y''
not y'''); 236/1-15 odd. Answers are in the back for even
209 & odd 236. Be neat, organized and use symbols properly.
Be sure that I can read the number of the problem. You may
access the Maple program I used in class under Maple Worksheets or here:
Problem 23 p. 210
as a template to check your answers on the homework. Read: Chapter 13 (def of Laplace transform. Do you remember improper integrals from Calc II?) (Chapters 11 & 12 are not in the syllabus for this course.) Test: A takehome test will be passed out on Monday on Chapters 8,9 &10 to be returned at the beginning of class on Wednesday. Note: A reminder: Monday, July 7 is the last day to turn anything in late according to the syllabus. |
| 7/2=W |
Read Chapters 9 & 10.
No test Thursday, perhaps next Tuesday. Note:
We can start doing homework on Chapter 9.
However, since I said none would be due tomorrow in class I won't collect
it tomorrow. But, you would be doing yourself a favor if
you started some today so you could as questions in class tomorrow.
Here are some to start with 209/2,8,19. Answers
in 7/3=R box. (I sent you an e-mail on this also.

Chapter 9. Project 5: Starting with the second paragraph on page 178 write down all the steps it takes to arrive at Theorem 2 on p179. Equations in the left-hand column, reasons in the right-hand column, as described in class. You are to do this in conjunction with 1 or 2 other persons. Secretary should be the first name on the paper and is due in class on Thursday. Very Important Note: Typo p177: On the second last line of page 177 starting with "Setting this..." it is written Fy(x,y) should be written as Fx(x,y) |
