UNIT OVERVIEW

This revision unit brings together all the major topics from Term 2. You will consolidate your understanding, identify gaps, and build the problem-solving skills needed for your examinations.

In this revision unit, you will:

• Apply trigonometry rules to problems in two and three dimensions
• Use the Factor and Remainder Theorems with polynomial functions
• Work through differential calculus from first principles to optimisation
• Solve analytical geometry problems involving circles and tangent lines
• Practise exam-style questions that combine multiple concepts

Why these topics matter:

• Surveying and construction: Trigonometry in 3D helps calculate heights and distances on building sites.
• Manufacturing: Polynomial functions model curves for product design.
• Business decisions: Calculus helps find maximum profit or minimum cost.
• Navigation systems: Coordinate geometry underpins GPS technology.
