Essential Mathematical Methods 1&2 has been specifically designed for students undertaking Mathematical Methods Units 1&2 and intending to proceed to Specialist Mathematics and Mathematical Methods 3&4, or just Mathematical Methods 3&4. The material is chosen from the revised Mathematics Study Design and supplementary material has been added to enable a thorough preparation for these Year 12 courses. The new book also features questions that require the use of a graphics calculator in certain exercises. The CD-ROM includes chapter sections that contain theory, worked examples and exercises linked to answers.
