Fundamentals of Differential Equations, Sixth EditionReview Date: 2006-11-11
so poorly writtenReview Date: 2006-06-27
page 513
"...diagonal matrices, which are square matrices with only zero (0) entries off the main diagonal (that is, a(ij)=0 if i does not equal j); and column vectors, which are nx1 matrices. For example:
A=
(3,4,1
2,6,5
0,1,4)
B=
(3,0,0
0,0,0
0,0,7)...
Then A is a square matrix, B is a diagonal maxtrix....."
WAIT BACK UP! I thought if you were a diagonal matrix then you had zeros for all numbers except for the diagonal....remember if you have i rows and j columns in a square matrix then the only time i=j is along the diagonal and didn't the book already says that a(ij)=0 if i doesn't equal j? So why does B(2,2) have a 0? Is it because not all values in the diagonal can be 0 or is it because there is a typo? I don't know but if I pull out my linear algebra book or perhaps surf the web I can find out...but isn't that a waste of my time trying to make sure these people are just using poor notation or pressed the wrong key? I think so. I certainly would never use this book again nor would I ever use it as a reference. I actually went and picked up another book for diff eq that I use along side this terrible book, and the only reason I keep this diff eq book by nagle is so I can refer back to the table of contents for topics when my teacher says which chapters the test are on.
Pretty Standard TextbookReview Date: 2005-05-26
===============================================================
"Given the initial value problem,
dy/dx = f(x,y), y(xo) = yo,
assume that f and the partial derivative of f with respect to y are continuous functions in a rectangle
R = { (x,y): a < x < b, c < y
that contains the point (xo, yo). Then the initial value problem has a unique solution phi(x) in some interval x0-delta < x < x0 + delta, where delta is a positive number."
================================================================
Using the phrase "assume that..." seems to completely de-emphasize the salient point which is that,
================================================================
IF f and the partial derivative of f with respect to y are continuous functions in a rectangle...
THEN the initial value problem has a unique solution phi(x) in some interval....
================================================================
But this is a fairly minor complaint, and mostly just a matter of personal taste. I am grateful that I had a good instructor though, as he was able to pull out the important points that were not obvious from the text.
On the plus side, the book has an excellent Student's Solutions Manual by Victor Maymeskul. For the most part, all the odd numbered problems were thoroughly worked and explained. I would highly recommend getting the solutions manual.
Bottom line, if this is a textbook for a class, don't worry about it. The book will be just fine, and a good instructor will be able to use it effectively. If you want a book for self study, this may not be the best at clearly explaining concepts, but at least with the solution manual you will have lots of practice problems you can work and check. For self-study, you might check out "Ordinary Differential Equations" by Morris Tenenbaum and Harry Pollard. I have not used it extensively, but it seems to be quite clearly written, and has generally received good reviews.
A very good textbook, just not quite right for meReview Date: 2007-01-13
However, I do strongly approve of the pedagogical approach taken by the authors. Their use of blue highlighting for the important formulas is eye-catching and effective. As I scanned through the book it was sometimes easier to determine the topic of a section by looking for the equations that were in blue. The exposition made the material easy to follow and the many worked and varied examples make the coverage complete.
I was also pleased to see the occasional theorem with proof. While courses in differential equations are largely, "give the technique(s), here is how to use it", it is still an upper division math course and an occasional proof is certainly reasonable and effective. The authors also include a short set of technical writing exercises at the end of the chapters and there are plenty of exercises with answers to the odd-numbered ones included in an appendix. While I don't think that I would ever make use of the technical writing exercises, I am sure that there are others who would take advantage of the opportunity.
In conclusion, even though I was impressed with this book, I doubt that I would adopt it. The differences between differential equation texts tend to be rather small, so the fact that this book is suitable for a two-semester sequence is enough for me to continue to look elsewhere.
An excellent textReview Date: 2004-06-23
Since my first differential equations class, I have encountered some difficulty understanding partial differential equations, particularly heat equations and vibrations of a spring. The textbook I use for my intermediate engineering math course that I am covering this material for does a sloppy and incoherent job. However, using this book as a reference I was able to break down the process to "discovering" partial differential equations and am on my way to understanding at least heat equations and vibrating strings rather well. This book also clearly facilitates the reasoning behind fourier series and transforms.
I highly recommend this book. Although I didn't have much choice in selecting it for my courses, its use after the end of the intended course certainly exemplifies its value.

Give Tom Berenger a Chance; He Deserves a Better Film Than This Badly Told B-MovieReview Date: 2005-09-02
Not much can be called original about the script of 'Sniper 3.' Thomas Beckett is sent to Vietnam, where he fought his war with his buddy during the war 30 years ago. But Beckett is informed that the friend who is supposed to be dead is now ruling the underground community as druglord (the idea inspired by 'Apocalypse Now'). And Beckett's assignment is to kill him.
Byron Mann appears as Sgt. Beckett's partner from Vietnam, and Thailand provides the convincing locations for the backdrop. Both actors did good acting, and the film tries to show the deeper characterization about Beckett, who talks about his old days, and even attends a wedding party (not drunk for that matter). The results of the efforts are not bad.
But the actions are so-so at best, with shoddy editing that often makes me wonder what is going on. For example, after Beckett's first 'hit,' a shoot-out scene at the rooftop begins, but as the film fails to show who is shooting (at) who, the sequence only shows alternately the confusing images of men shooting guns and men who got shot. And I still do not fully understand what happened in the last chapter, the terribly hurried and awfully incoherent wrap-up that comes with bamboo impalement. Excuse me, but I thought this is about a sniper's story...right?
Though the film is watchable thanks to the actors and locale, 'Sniper 3' reminds us of the fact that we really need somebody who can save Tom Berenger from this Grade B straight-to-video hell.
AND ALL OF THE ABOVE - [COMMENTS]Review Date: 2005-09-27
Beckett is back - [not with the honed body we would have like to see] but still a strong masculine charisma.
Yup! being done dirt to by his superiors? They want him dead too! That would eliminate all their loose ends.
I was waiting to hear that he had gone back and eliminated them.
I did get what I was waiting for though. A shot that seems impossible to make. Doing what seems impossible is what we look for in our Super Heroes and especially our Snipers.
Come on you guys. What is with you that you cheapen our good movies [almost good] with barnyard language.
I really get disgusted with woman [and men for that matter] with vulgar mouths. I blame this on the writers and directors who seem to have illiterate minds.
Vulgarity is not a sign of masculine charisma - just low-bred mongrels.
I enjoyed Beckett - I ignored the crass language - and I love the shot! For Mature audiences only.

Family Background Plays A Big Part in Both, so Beware.Review Date: 2006-10-18
This book traces the interconnection of both within and across our species. Family are the biggest hindrance for certain people, like those highly sensitive. The brutes of society set out to hurt these special individuals with anger and guilt as their instigators. These aversive episodes are the opposite of kindness and empathy by others, and cognitive attributes suggest new paths for making sensitivity a blessing, and not a handicap. You learn about prosocial and antisocial behaviors such as selfishness ans separation distress among the young. Social play such as dreams have a part in overcoming other's aggression.
"I rose before dawn. The dream awakened me and I could not fall into sleep again. In the first passing freshness of the day, I scattered grain for the geese... The sun came up saffron, rose, and scarlet from the eastern hills, promising heat." The brighter side of human nature is Altruism and Empathy. There is a vast difference between aggressive and assertive actions to discipline confrontations. Many years ago, I sat in on a few sessions of a class on teaching Southern women to become aggressive by a Chicago male. When I wouldn't participate, he asked why. I told him I can be assertive when necessary, but never aggressive. Lately, I've changed my mind about that. Denying your emotions any longer will only delay the inevitable. After three years of being harassed and stalked by another being (not exactly human), I have decided it is time to take the aggressive, combative reaction. There is only so much a victim of such abuse can take. The function of emotions is to protect one's safety, physical and mental. Sometimes, it behooves the non-violent to take up for themselves when she has no one else to do it for her.
Aggression is not always bad. Sometimes it is needed for protection. It all depends on the individuals involved and the harshness and depth of a dangerous situation. I've been able to bluff my way out of a hostage situation which would have ended in death had I shown fear. But it left a scar, and now I warn the officials that a part of town is dangerous for bus riders and even ordinary women in particular. There is such a thing as taking this altruism thing a bit too far and endanger innocent people.
