## About the Book

This book has been written for the IB Diploma Programme course Mathematics: Applications and interpretation HL, for first assessment in May 2021.

This book is designed to complete the course in conjunction with the Mathematics: Core Topics HL textbook. It is expected that students will start using this book approximately 6-7 months into the two-year course, upon the completion of the Core Topics HL textbook.

The Applications and interpretation courses have a focus on technology, and this book is written with this focus in mind. Where appropriate, graphics calculator screenshots and instructions have been provided to help students use technology to solve problems. An algebraic approach to solving the problem may also be included for completeness, and to help the students enhance their understanding. The material is presented in a clear, easy-to-follow style, free from unnecessary distractions, while effort has been made to contextualise questions so that students can relate concepts to everyday use.

Each chapter begins with an Opening Problem, offering an insight into the application of the mathematics that will be studied in the chapter. Important information and key notes are highlighted, while worked examples provide step-by-step instructions with concise and relevant explanations. Discussions, Activities, Investigations, and Research exercises are used throughout the chapters to develop understanding, problem solving, and reasoning. A large number of more difficult questions have been included to challenge the HL student.

Discussion topics for Theory of Knowledge are included throughout the book.
