• Practice Workbook: 43 pages, 102 problems from basic to exam standard, with room to work on the page and a complete answer key
• Formula Reference: 9 pages with every identity and formula of the volume, ready to keep on your desk

HOW IT IS WRITTEN
• Every identity is derived, not just listed, so you can rebuild the one you forget in the exam
• Trigonometric equations step by step: the three general solutions, solutions inside an interval, and the standard methods (quadratic in one function, factoring, homogeneous equations)
• Every step is written out, one operation per line, so you can follow it with a pencil
• Tip and warning boxes flag the mistakes that cost marks

WHO IT IS FOR
• High school students learning trigonometry, from the first triangle to the graphs
• Students heading into precalculus or calculus who need trigonometry to be automatic
• Students revising for a test or an exam
• Parents and homeschoolers who want a clear, complete course

WRITTEN BY
A mathematician with a master's degree in mathematics, who has spent years in teaching: as a professor of mathematics in the classroom, and as a tutor in around 3,000 one-to-one lessons.
