Letters & Devotion Grade 12: Precalculus: Functions, Trigonometry, and Mathematical Modeling

Description

“Precalculus: Functions, Trigonometry, and Mathematical Modeling” (Grade 12) is the Grade 12 math volume in the Letters & Devotion homeschool print curriculum. It runs 571 pages and contains 81 lessons (Math: 81 lessons), with 607 practice-sheet problems and 165 mastery/unit-check items built directly into the book, plus a full answer key at the back. Every lesson is written for a parent with no teaching background: each one opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet that may be copied for household use. Every practice sheet is answer-keyed step by step, not just to a final number. This is a standalone, black-and-white, 571-page printable PDF at 8.5 x 11 in (print at home or at a copy shop); no login, subscription, or additional purchase is required to use it. (The same lessons are also taught aloud by Clara, a built-in AI teacher, at lettersanddevotion.com, with the first 30 days free, for families who want that option; the print book stands on its own without it.)
