College Algebra
The textbook covers a full range of subjects expected in most college algebra classes, including some topics--such as systems of equations and matrices--that delve into Linear Algebra. It is worth noting that while the text includes large numbers of exercises for students to solve, formal proofs are largely ignored, so the text is not suitable for a class with an emphasis on the latter. The text has several calculator-specific problems, complete with display printouts, for those who allow or encourage calculator usage in class.
There did not appear to be any errors in the chapters I reviewed.
Since the material is foundational for many subsequent subjects, there is no danger of the mathematics losing relevance. Updates should be simple to perform.
Some of the solutions provided for example problems are rather verbose and potentially confusing for students depending on their experience level. At times the casual tone of the explanations, problems, and footnotes can be distracting as well. The somewhat informal style of several sections and questions may be hit-or-miss among both students and instructors, depending on the classroom.
Terminology and tone remain consistent throughout, with no notable exceptions.
There are many questions at the end of each section, allowing instructors to narrow down a preferred list or to separate specific problems to be used for review materials. The sections themselves can be easily reordered or modified to suit the class at hand if instructors prefer to focus more or less on individual sections in a chapter.
We typically switch the order of the first two chapter subjects, introducing the basics of linear and quadratic equations before defining functions and transformations in more detail, but the order can work as given too. The answers for section exercises would be better placed in a separate index rather than directly after the corresponding problems so students do not need to flip or scroll through pages of solutions between sections, though this is more of an issue in the physical text than the digital one.
An excellent feature of the digital version is the hyperlinks to previous definitions in the book or separate webpages for concepts like the Pythagorean Theorem or Newton’s Law of Cooling. It is a very useful way to review or learn about recurring formulas without flipping back through physical pages constantly or bookmarking several sections. Even the Index has direct links to appropriate pages. No issues exist with graphs and images, which are typically clear and relevant.
I did not notice any glaring grammar mistakes in the text.
There is somewhat of a focus on US data, units, and references, which could be expanded to other countries, systems, or cultures without needing to alter the writing style too much.
The text is solid in its given form, but it may need extensive modification to fit a particular course more effectively. Thankfully, the ease in doing so makes it a reasonable base for a college text.
