What You Actually Need to Know About This Book
The Hill Ryerson Advanced Functions 12 textbook is the standard Ontario Grade 12 mathematics resource for functions, limits, and introductory calculus. It's what you use if you're writing the UACE exam or preparing for first-year university math. The book itself is decent but dense, and the explanations sometimes skip steps that most students actually need to see. Here's the practical reality: the problems in the back of the chapters are well-constructed but many of them assume you already understand the technique before they ask you to apply it. I ran into this repeatedly. Chapter 5 on rational functions has a set of synthesis problems where the text shows you how to simplify one example, then immediately asks you to factor and simplify a completely different type without walking through the bridge between them. My workaround was to treat the worked examples as templates rather than complete explanations, then go to the end-of-chapter review sections where the problems are slightly more scaffolded before attempting the harder skills practice set. The book covers polynomial functions, rational functions, trigonometry, exponential and logarithmic functions, and introduces limits and derivatives. That's the full scope. If you're struggling with any of those sections, the issue is rarely the book itself. It's usually that you haven't solidified the algebra underneath it.
I'll be honest about where this textbook falls short. The treatment of limits is very surface-level. It introduces the concept but doesn't build the intuition you actually need for later courses. The derivative sections cover basic rules but skip a lot of the why behind chain rule applications that show up in university. If you're using this book solely to pass the course, it works. If you're using it to truly prepare for calculus at the university level, you will need supplementary material. I recommend pairing it with worked example videos or an older edition of a similar text that goes deeper on the theory side. One counter-intuitive thing about this book that trips people up: the chapter on trigonometric functions comes early, and the book assumes you already remember SOHCAHTOA and unit circle values cold. Students who haven't kept precalculus trig fresh tend to stall out in Chapter 4 because they're fighting two battles at once. Spend time reviewing the unit circle and reciprocal identities before you open that chapter. It saves roughly two weeks of confusion. The logarithm section has a common trap in the problem sets. The exercises on solving logarithmic equations often produce extraneous solutions, but the answer key doesn't always flag which ones are invalid. I caught this when my calculated answers didn't match the back of the book on problem set 5.3. The fix is simple: plug every solution back into the original equation and check for negative logarithm inputs. It takes thirty seconds per problem and catches most of those errors.
If you're downloading supplemental material or looking for solution guides, be careful about quality. Many sites selling solution manuals for this book have outdated editions or incorrect work. The seventh and eighth editions are the most common, and they differ in problem numbering. Make sure whatever resource you're using matches your edition. Mismatched editions waste more time than anything else I've seen with this textbook. The best way to use this book is not to read it cover to cover. Go to the specific chapter you need, work through the examples yourself before looking at the solutions, then attempt the A-group problems. If you can do those, move to B. Skip C until the exam is close. The pacing of that approach typically covers the required material in about six to eight weeks of regular study.
