Level 3 Trigonometry Learning Workbook covers NCEA Level 3 Achievement Standard 91575 (Mathematics 3.3): Apply trigonometric methods in solving problems. This standard is internally assessed and worth 4 credits.

Features:

• concise theory notes with brief, clear explanations
• worked examples with key concepts and skills explained
• relevant sets of exercises for student practice
• answers to all exercises, provided in the back of the book
• a set of practice revision questions
• A handy index

It covers the use of trigonometric expressions, equations and graphs in order to solve problems, including trigonometric identities, the properties and graphs of the reciprocal trigonometric functions, and the general solution formulae. Harder problem solving may require the forming of a trigonometric model from contextual information, and the use of a logical sequence of steps of reasoning in order to find a solution.
