✦ Synopsis

Maths in Focus 12 Mathematics Extension 2 is a new book written for the Mathematics Extension 2 course. Each chapter begins with a table of contents, chapter objectives and a Terminology glossary and graded exercises include HSC-style questions and realistic applications. Investigations explore the syllabus in more detail, providing ideas for research projects and modelling activities and Did you know? sections contain interesting facts and applications of the mathematics learned in a chapter. Each chapter ends with a Test Yourself revision set and Practice sets (after several chapters) include exam-style questions from various chapters. Syllabus gris and codes, answers and an
