5 comments about Multiple View Geometry in Computer Vision.

1. The book succeeds in introducing you to the world of multiple view geometry. Specially the math and geometry concepts associated with it. In my research, I had to work on stereo images and this book provided very good information about it. The algorithms are presented very clearly and have been easy to implement (at least in Matlab).

   It's a good reference book to have.




2. The first edition of this book could have been much better written. It took up a lot of topics, but treated each in a summary fashion. In fairness, though, I must say that this may be as good as any other book with its aim and scope, and better than some. Any writer on computer vision faces the problem of guessing who the reader is likely to be and what the reader's background is. Also, each of the various topics really merits a sizable book. In particular, the mathematics needs a truly mathematical treatment in a separate book. I have not seen this second edition, but there was room for improvement over the first edition.



3. My lab has the first edition of this book. Everyone likes it. That's why we order a second book. I have not read through the second edition yet, but this book rocks!



4. The book has a lot of valuable information for those who are working in computer vision. The book however is fairly terse on many subject and requires careful reading.



5. I find the book very useful, it is full of practically useful content. Formulas, theorems, lots of examples and illustrations. Overall very easy to read and understand, though requires you to recall your forgotten mathematical skills. The book does present what it claims on the first pages, so read the abstract and judge for yourself if you need the book. For my purposes, I found it to contain all the material I needed to perform certain image photo transformations and compositions. There is also lots of reference material, in terms definitions, formulas and theorems with proofs. And it's good to have it all in one place.
   
   Overall I would say it is worth the money.

5 comments about Euclidean and Non-Euclidean Geometries: Development and History.

1. This is the fourth edition of a particularly fine text
   by Marvin Jay Greenberg. If you want to learn about
   Euclidean and non-Euclidean geometries---the great contributions
   of Bolyai and Lobachevsky---this is the place to do it. The
   book is authoritative but warm and inviting. It is full of
   good history and full of good mathematics.
   
   The fourth edition has a good deal of new material. Greenberg
   explores some of the subtle logical issues, and also some
   of the tricky points of geometry. He makes far-ranging
   commentary on how non-Euclidean geometry fits into the modern
   flow of mathematical thought. There is even some discussion
   of Perelman's proof of the Poincare conjecture.
   
   Even a reader without a strong mathematical background will get
   a good deal from dipping into this book. It gives a great
   sense of what the mathematical enterprise is all about, written
   by a distinguished mathematician (who was also my teacher many
   years ago). I consider this work to be one of the treasures on
   my bookshelf.



2. This is a very good book about Euclidean and Non-Euclidean Geometries.
   Well written, this book introduces to the lector in the historical context of the development of the Geometry.
   I enjoyed very much.
   
   Why is it so cheap, now (April, 2008) ? Because, this is the 3rd edition and exists a new 4th edition since September 28, 2007.



3. The Fourth Edition of M.J. Greenberg's textbook is a wonderful addition to the geometry textbook literature. No praise could be higher than to say that it is even better--indeed, a good deal better--than the highly regarded earlier editions. There are important revisions to each of the chapters and appendices, some of them extensive. As Greenberg aptly notes: "this book is a resource for a wide variety of students, from the naive to the sophisticated, from the non-mathematical-but-educated to the mathematical wizards." In this reviewer's opinion, Greenberg's fourth edition along with the Robin Hartshorne's mathematically more technical Geometry: Euclid and Beyond (2000)--a text to which Greenberg repeatedly makes reference--are far and away the most informed, up-to-date, and historically and philosophically sensitive geometry texts on the market today. No one with an interest in the foundations of geometry can afford to be without copies of these two great works.



4. I had the pleasure of reading and studying the Second Edition of this text while in college. This course with this text was my favorite course during all of my undergraduate math courses.
   
   Being a fan of the subject, I was eager to see the new Fourth Edition of the text. The Fourth Edition is quite expanded from earlier editions, going past the wonderful main story of the Parallel Postulate - told better by Greenberg than any other author, IMHO - and diving into the different non-Euclidean geometries that "open one's eyes" by setting aside the "obvious axiom of a unique parallel". The last chapters are greatly enhanced, with a superb presentation of the issue of straightedge and compass constructions in the Hyperbolic plane.
   
   This presentation of Non-Euclidean geometry is more serious than the "popularized" books on advanced mathematical topics. If you're looking for a "light, fun" reading of this topic, this is not the book for you.
   
   I feel that the real power of the story of the maturing of intellectual thought, so brilliantly portrayed in the story of the Parallel Postulate, must be experienced, through the effort (and often hard work) of actually **doing** geometry, rather than just reading lightly about it. If you want to dive in and actual experience geometry (and the consequent rewards), then this is the book for you. The explanations are magnificent, the problems are wonderful (and, at times, very challenging), all culminating in the "wow!" of modifying the Euclidean way of thinking to a new and beautiful alternate geometrical universe.
   
   As other reviewers have noted, this text reads like a great novel - a drama involving geometry. If PBS/Nova ever make a "What does Parallel mean anyway?" show, this text will be the basis for that show.
   
   I believe this Fourth Edition can be considered the quintessential text on this topic, on which all future discussion of the topics can be based, including both the introductory materials, as well as moving to the forefront of research on many topics in Hyperbolic geometry.
   
   For a university course, weaker students will find this text quite challenging, and possibly too hard. For average students, this text will provide sufficient challenge and interest, and ample areas in the text that will not overwhelm. For advanced students, this text will certainly challenge in many different directions and interests, both in the later chapter discussions, and various problems throughout.
   
   Greenberg's writing is meticulous - you will never find an error, a comma out of place, nor a sentence that is not perfect.



5. There are already 16 reviews of this excellent and exciting book so i will only add that some people complained about the great number of results of the core text the reader is asked to search proofs as exercises. For a mathematically inclined reader this is not such a big trouble because most of these exercises have extended indications which math-inclined people can easily transform in a complete and sound proof. For myself i had almost no trouble with them.
   So the difficulty is only for people who did not have a mathematical training as college junior. Even in this case they can learn a lot about the nature and purpose of pure mathematics and, if they are persistent and enduring, how to read and write mathematical proofs.
   As a Frenchman i wonder why such a good book has not been translated in French, it really deserves it because books in French on geometry are so often unexciting and boring.

4 comments about Trigonometry (Cliffs Quick Review).

1. I'm a (returning :P) university Freshman preparing for the College Board CLEP tests. I was already familiar with the material covered in this book, but needed to refresh my memory. This review turned out to be *exactly* what I needed.

   The author's ability to explain the material to the student are just shy of enlightening. The discussions & theorem proofs are written in a very concise, clear style.

   I'm a big advocate of the Cliff's QuickReview series. Intended as a course supplement, these books are also *GREAT* for students wanting to refine their skills. Most of them are also very accessible to students with less familiarity on the subject; trying to learn it for the first time.

   After reading this, I bought the Calculus & Differential Equations QuickReviews & I'm looking forward to reading them!




2. After several years in a corporate engineering job, I started moonlighting as a math tutor. The Cliff's Quick Review Guides are wonderful to have in my "back pocket" when I need to quickly look something up that is covered in dust in the "archives of my brain."



3. This book seems to be pretty nice, until you start finding all the super horrible mistakes that are thrown in ever couple of pages. They are all do the this book not being edited, and make it a hassle to read as you have to second guess everything that is written. I got about half way done and the mistakes turned me off so bad I put the book away and don't intend to read from it again. This book could have been a real nice book but the mistakes are just too horrible to look over.



4. You credit card gets charged and there is no refund. Then you spend several hours trying to get the download and it does not happen. Better to order from http://www.cliffsnotes.com/WileyCDA/

No comments about Symmetry: The Ordering Principle (Wooden Books).

3 comments about Calculus: Concepts and Connections.

1. -The definition of e is given as lim(1 + 1/n)^n, with no motivation, and before
   limits are discussed. (From a book purporting to emphasize concepts!)
   -No proof of the general power rule appears (it's an easy application of
   logarithmic differentiation).
   -No formula is given for the derivative of e^f(x).
   -A "proof" of the mean value theorem appears in the appendix. It invokes
   Rolle's theorem, but Rolle's theorem is not proven. (Reason: Rolle's uses the
   extreme value theorem which is not mentioned in the book. It also uses
   Fermat's theorem, which is not covered until 40 pages after Rolle's in this book.)
   -Newton's method is introduced before students have experience solving
   equations of the form f(x)=0 (e.g. finding critical numbers). So there is no
   motivation. Also it is done before graphing, so students have no basis
   for making their initial estimate.
   -Part 1 of the fundamental theorem of calculus follows in 2 lines from part 2.
   This text makes no mention of this; it gives separate proofs of each part
   using the MVT.
   
   In general, this text seems pretty disengaged from the underlying mathematics.



2. Gave me a good understanding of Calculus concepts, I needed it to go through a pre-req for my Masters in Computer Science. Would give it a 4 star.



3. Another reviewer has pointed out some of the shortcomings of this text, and those are some pretty critical problems. I would not recommend this text alone, but it is a pretty good supplement. Specifically, I found the discussion of curvature to be brilliant.

5 comments about Discovering Geometry: An Inductive Approach.

1. OMG! This book was so complicated to understand. They expect you to know everything. Because of this mindless crap, I failed Geometry and had to take the regular one. And the worst part is that they don't include enough examples to explain how to work the problem. I wouldn't recommend this God forsaken piece of crap to anyone who wants to do good in Geometry.



2. This book was the bane of my existence throughout 9th Grade Geometry. Having had a year of a real math book this year I am finally able to realize just how stupid the book was. It treats the student like he or she is about two years old, does not provide the information necessary for exam review, and is far too colloquial in general. In addition, it has no answers in the back, just "Hints" in the back of the book that either do nothing at all to help or solve the problem completely without explanation. It also says "SHAME ON YOU" if one looks at the hints without first trying the problem. Personally, I don't enjoy being chastized by a math book, especially one with such a bad approach to Geometry,



3. This is by far the worst text book i have ever seen or had to use. Unless you are an expert at geometry or have a great teacher this book will be useless to you. It gives no anwsers to the odd problems and there is no glossary. Because of this i dont know if my answers are right or wrong. I usually try to find the way to solve problems myself but since this book gives no examples on how to do anything i cant. I feel sorry for any other person who is like myself, and is forced to use this sorry exuse for a text book.



4. I am an eighth grader taking Geometry, so it is obviously advanced. However, this book is not helpful AT ALL in learning. It is so frustrating to not even have a glossary in the back to find definitions, and the book does a very bad job of explaining tough concepts. If you are a teacher, please try a different book.



5. This geometry book is clearly written, has interesting visuals, usea excellent teaching strategies, and is simply the best book available. High school students at various levels seem to respond well to the textbook. I know math teachers who think this book is far superior to any other.
   
   I wish they'd had geometry books like this one when I was in school!

5 comments about Calculus With Analytic Geometry.

1. It definitly helps one who want to master Calculus or join the Calculus competiton of any kinds.

   It better than "Calculus With Analytic Geometry, Seventh Edition" for it give you some useful appendixs and very simplify than it. It does not includ differential equation for as the author said that it is not useful when there is a full course on differential equation!!!




2. Another MIT student here... unfortunately not all calc. classes at MIT has stopped using this book. As a result the majority of our class is hopelessly lost... and this is at MIT!!!... now that's a testament to how bad the book is... Things aren't explained well, the examples have nothing to do with the actual problems, and without the "space wasting" graphics that so many other books have it's difficult to visualize what Simmons is talking about, and despite popular opinion visualizing what you are doing is very important to calculus. I'm relying on my HS calc book to get me through the course.



3. This book is perfect if you are looking for a book that has a nice balance between theory and application. Theory is presented on an as-needed basis and there is more in the appendix if the reader is so inclined. This was an excellent book for me my freshman year and it has been a good reference for me throughout my math career. It is a nice stepping stone on the way to spivak.



4. I have a big, dirty secret: I needed three tries to get through calculus. Needless to say, I went through (or at least started) three calculus books. The third of these was Simmons' first edition of the current volume. Dr. Simmons takes a historical approach to the material, following discovery after discovery. While today we define the derivative in terms of the limit, this definition (and the delta-epsilon proof machinery beneath the limit concept) came after the geometric notion of the tangent of a curve. I found it enormously helpful to know where I was going before I started. And why not? The great mathematicians that built the rigorous foundations beneath the calculus all knew where they had to end up.
   
   One other topic that Dr. Simmons enjoys is arithmetic series. This topic unfolded like a flower during its presentation. As I moved into computer science, this provided valuable background to some of the iterative methods of calculation I was exposed to.
   
   I might have a different perspective, though; George Simmons was my Calc 2 prof :-)



5. This book virtually made me love mathemathics. It's a book with an unique set of features in it's appendix, and the writing style of the author is almost like you are actually reading a great novel about calculus.

2 comments about College Algebra and Trigonometry (4th Edition) (Mathxl Tutorials on CD).

1. The book is decent. But is not a great text book. It's highlihgted formulas, etc... are very helpful, but it doesn't seem to explain a lot of things in a way to make them easily understandable. I have used many different math books, and I would not use this one unless you are teaaching extremely bright students.



2. I truly did enjoyed being a client of this seller! I got a perfect product with a perfect service and a quick delivery! I felt secure with my order.
   Thank you very much!!

4 comments about Finite Mathematics (9th Edition) (Mathxl Tutorials on CD).

1. As a reviewer and educator, I encounter many textbooks that can be used in the lower level classes such as basic statistics, algebra, precalculus and finite mathematics. Since the material to be covered in these classes has been established by consensus, it is a rare occasion when there is a significant difference in coverage. In addition, there is a natural order to many of the topics, so the differences in sequence also tend to be minimal. All of this leads to a routine sameness of the books, especially when examined by someone experienced in the topic.
   Therefore, when examining a book for adoption consideration, my primary concern is how easy it will be for the students to read it. This requires that you intentionally dumb yourself down, reading the explanations in detail, looking for simplistic clarity. If a book has that feature, then it is most likely a good choice. With the exception of including solutions to a large percentage of the problems, all other aspects of the book are secondary. (I consider the lack of solutions to problems in a math book to be a fatal flaw.) In general, I consider the inclusion of more problems of the same type to be trivial padding; after all, the value added by including ten more routine matrix addition problems is minimal. In finite mathematics, it is possible to include problems based on circumstances that actually occur in the real world. The cost of manufacturing some items is in fact locally linear and the allocation of resources can be described by a matrix. Therefore, the realism of the applied problems must also be a consideration when examining a finite math text.
   With these conditions of acceptance established, I can say that this book passes the test. The explanations have the simplistic clarity that students need and solutions to many of the problems are included. Many problems demonstrate reasonably practical conditions where finite mathematics is used in the world, and the appropriate background for the problems is given. While no decision has yet been made concerning what book to use next year, this one has been placed on my list of the top three finalists for further consideration.



2. I took an online class over the summer and used this book. Eventhough the teacher was not helpful, the book was. All the exercises were extremely helpful and the text was simple and easy to read. I would recommend this book for any who has to take this class.



3. This book was only used for one semester. It is in great condition looks brand new. I bought it brand new and kept it in the same condition.



4. I purchased this book brand new and full priced because it is listed as havinga MathXL Tutorial on CD. I felt the aid of interactive instruction would be beneficial. Since having recieved this book and inquiring of Amazon, I find the book does NOT come with a CD but with an online address for a website with instruction which costs and ADDITIONAL $35.00 to access. The title is incorrect and misleading, and making this transaction with Amazon has been disappointing. I will think twice before I make another.Finite Mathematics (9th Edition) (MathXL Tutorials on CD Series)
