Phoenix Senior Maths Topics provide thorough and detailed explanations, worked examples, summaries and practice exam questions on essential senior maths topics. Each book is a detailed treatment of a topic selected because of its importance in senior maths. They can be used at school, to supplement the textbook, providing more detail and exercises, and at home, to aid home study and exam preparation.

These books are for senior secondary students, particularly those who:

• want to study a topic in more depth
• are having difficulty with a topic

 Phoenix Senior Maths Topics books can be used:

• to learn and understand the topic: a full and detailed treatment of the topic with clear step-by-step explanations and plenty of worked examples.
