This book was required by my college professor for an intro discrete math course, and myself and many other in my class felt that it was pretty bad for an intro class.
There are far too few examples in this book, so just when you think you might be understanding the content, the book leaves you high and dry, hoping you really comprehended its content.
Years later, looking back at this book, its not terrible at all, now that I have more foundational knowledge. But this book can be a tough read for some.
They don't have instruction on some basic knowledge, but I finally find the answer from the key of one exercise question to finish another one.
Truly terrible book. Don't understand why a lot of teacher require this book.
I'm a math enthusiast, so I also bought copies of Grimaldi's and Epp's Discrete Math texts, and for this class I also needed to borrow copies of number theory texts for the section on number theory, logic texts for logic, etc. It's kinda sad in the state of things that one has to go to outside sources for so many of these topics... but Rosen makes you do it.
My issues on logic: They don't explicitly tell you that a function P(x,y) holds only for objects placed into the function. There is a problem in the section of nested quantifiers where the function is given as P(x,y) but then the solution uses x and y for something totally different. The book leads you to believe that P(x,y) means "property P holds for 'x' and 'y'" but with a function the property is static and the letters are dynamic. The book explains functions from the perspective that if you see P(x,y) then that property holds for x and y, and the specific problem I'm talking about will lead you astray when applying the logical construction; textbooks should be clear enough that the student doesn't have to go to the teacher on simple concepts like this
My issues truly began in Chapter 3. The pseudo code they use is loosely documented and assumes the reader already knows some programming because the entire section on algorithms was greek to me until a study partner who is a programmer by living gave me a quick crash course in programming that clarified what was going on in each step. The section on Big-O notation could have been simplified if the author simply said "we need to create a function that will be bigger than what is stated, and define 'k' as the beginning value where this is true and 'C' is the total sum of the coefficients that also guarantees this." The book takes a 5-6 page approach that buries this simple concept into obtuse mathematical jargon. I can't stress enough how bad the book covers this. (Epp's text with depictions of graphs that explicitly state the difference between Big-O, Big Omega, and Big-Theta was valuable to clarify this topic.)
Number theory is covered haphazardly, introducing div and mod before discussing the nature of numbers and primes. Div and mod are absolutely essential to number theory but the order of presentation serves only to confuse students. I grabbed a number theory book, "Elementary Number Theory" by David M. Burton and that text covers number theory in a much less confusing light than Rosen's text. (These books should all be in your school's library.)
Another book, suggested by my Professor, was Polya's "How to Solve it." This book locks you into the kind of thinking you need to be doing to handle proofs (and other types of problems.)
In short, if you're REALLY good on your mathematics... like you got > 4.0 in high school you might find my observations wrong. But if you are coming from the other direction, and are rising up to that level... this book just doesn't get you there without a TON of outside help. I suppose if nothing else, this book taught me how to use my library for supplementary materials as not a single chapter went by without a need to find things outside of the text.
