Product Details
- Trigonometry doesn’t have to be a table of values you memorize and hope to remember on test day. This workbook builds every concept from the ground up — so instead of memorizing, you understand.Starting with the geometry of special right triangles, you will discover exactly where the 30-60-90 and 45-45-90 ratios come from, why SOHCAHTOA works, and why tangent is slope. From there, the unit circle stops being a mysterious diagram you have to memorize and becomes something you can rebuild yourself at any time — because you built it, step by step, from the Pythagorean Theorem.The final section introduces reference angles: first how to find them, then how to use them to evaluate any trig function in any quadrant without a calculator.What’s inside: • Section 1: Special Right Triangles • Section 2: SOHCAHTOA and the Six Trig Functions • Section 3: The Unit Circle • Section 4: Reference AnglesEach section includes a concept introduction, fully worked examples, practice problems with an answer key, and a formula sheet. No prior trig experience required — just a solid foundation in algebra.Part of the Pre-Calculus Mastery Series by Morgan K. Mead.
