How to Actually Get Value Out of This Textbook
The AmSCO Algebra 2 and Trigonometry textbook is a standard high school resource that covers polynomials, logarithms, trigonometric identities, and sequences. It's widely used in New York schools because it aligns closely with the state's Algebra 2/Trig curriculum framework and the Regents exam format. The layout is dense. Each chapter runs long, and the practice problems range from straightforward drill to genuinely tricky multi-step questions that catch students off guard. I've worked with this book across multiple years of classroom teaching and tutoring. One specific issue stands out. Students regularly struggle with the section on proving trigonometric identities. The book presents them in a proof-heavy format that assumes students already understand the underlying algebra. I had a student who kept getting stuck at step two on identity proofs involving reciprocal functions. The workaround was to have him convert everything to sine and cosine before attempting any manipulation. That single shift made the proofs tractable for him. It wasn't in the book's guidance, but it's a practical fix that works consistently.

The book is structured with clear chapter divisions. Chapter 1 moves through polynomial operations and factoring. Chapter 2 introduces rational expressions and equations. The trigonometry content kicks in around Chapter 12 and continues through the end, covering unit circle definitions, graphing sine and cosine, solving triangles, and establishing key identities. The review sections at the end of each chapter are useful for Regents prep, though they don't always mirror the exact difficulty of the actual exam questions. One counter-intuitive point that students miss: the order of topics matters more than the book implies. The logarithm sections in Chapter 8 rely on exponent rules from Chapter 1, but also on radical simplification skills from Chapter 3. When students skip back to refresh those earlier skills, they move through the log material significantly faster. Reading linearly without returning often creates gaps that slow everything down later. Another thing worth noting about the trigonometric identity section. The book introduces the Pythagorean identities early, but it doesn't spend enough time explaining when NOT to use them. Students will try to apply sin squared plus cos squared equals one to problems involving tangent and secant when a different identity would be far more direct. Learning which identity to reach for first saves substantial time on exams. I had students cut their identity proof time roughly in half once we started categorizing problems by the dominant function rather than working top to bottom on the page.
There are legitimate downsides to this textbook. The problem sets are extensive but some are repetitive. You'll find five or six nearly identical polynomial division problems in a row that don't add new skill requirements. On the other hand, the harder problems near the end of each set are under-marked. Students breeze past the easy ones and never attempt the challenging ones, which are the ones most likely to appear on the Regents. I recommend doing at least three problems from the final third of each exercise set even if the first dozen feel too easy. Another limitation is the treatment of inverse trigonometric functions. The explanations are brief and the graphing section glosses over domain restrictions. This is a known weak spot. I paired this textbook with additional worksheets focused specifically on arcsin, arccos, and arctan graphs and their restricted domains. Without that supplement, students commonly make errors on Regents questions involving inverse trig composition. If you're looking for a digital copy, the textbook is published by AmSCO School Publications. It's available through major textbook retailers, school supply stores, and occasionally on platforms like eBay in used condition. Some school districts provide it through Google Classroom or similar LMS platforms. Make sure you're getting the correct edition — the 2013 and later editions updated the Regents-aligned content, and earlier versions may not match current exam requirements.
The supplementary materials are worth using. The AmSCO study guide that accompanies the textbook has separate answer explanations for odd-numbered problems, which is useful for self-study. The chapter tests in the back are closer to actual Regents format than the chapter review questions. Working through those under timed conditions is one of the more effective prep strategies available. Don't expect this book to be sufficient on its own for Regents preparation. It covers the required content, but the exam includes question types and cross-topic synthesis that the textbook doesn't always practice. Combine it with released Regents exams from the New York State Education Department website and targeted practice on weak areas. That combination typically produces better results than any single resource alone. One edge case that comes up frequently: students who need the book for a college placement exam rather than a high school course. The AmSCO text goes deeper into trigonometric proofs than most college placement tests require, which means students studying from it may over-prepare on identities and under-prepare on practical graphing and application problems. If your goal is placement testing rather than Regents readiness, I'd recommend supplementing with a more application-focused resource or skipping the heavier proof sections entirely.
The book itself is a solid reference for the core curriculum. It's not the most engaging read, and the writing can feel dry at times, but the mathematical content is accurate and the progression is generally sound. The main value comes from how you use it, not from the book alone. Work the harder problems, return to earlier chapters when concepts connect, and don't ignore the Regents exam materials that come out each year. Those three habits make a noticeable difference in outcomes.
