Description

Analysis & Approaches HL – Textbook

This book has been written for the IB Diploma Programme course Mathematics: Analysis and Approaches 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 Mathematics: Core Topics HL textbook.

The Mathematics: Analysis and Approaches courses have a focus on algebraic rigour, and this book is written with this focus in mind. 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.
