Trigonometry Series - Concepts and Formulas™
Vectors (TRG-CF8)

This sheet provides a comprehensive review of all of the most important topics, concepts and formulas fully covering vectors. Each concept is explained in detail, with detailed illustrations. Unlike charts and notes, this Concepts and Formulas™ sheet answers questions about how to use the concepts - how to actually solve problems with them, it doesn't just list facts and formulas. There is even an example, or two, for each concept, to help you to nail down the central ideas.
