UNIT OVERVIEW

This revision unit brings together everything you have learned in Grade 12 Mathematics. You will consolidate skills across algebra, calculus, trigonometry, geometry, statistics, and probability—the topics tested in your NSC examinations.

In this unit, you will:

• Consolidate sequences, series, and financial mathematics
• Master function analysis including inverses, exponentials, and logarithms
• Perfect calculus techniques for optimisation and curve sketching
• Strengthen trigonometric problem-solving across all identities and applications
• Refine Euclidean geometry proofs and analytical geometry
• Polish statistics and probability skills
• Develop time management strategies for the 3-hour examination papers

Why this matters:

• Investment planning: Financial advisors use annuity formulas to calculate how monthly savings grow over time.
• Engineering: Civil engineers use calculus to find optimal gradients for roads.
• Medical research: Statisticians use regression to study relationships between health factors.
• Architecture: Geometry theorems help calculate sight lines in stadium design.
• Navigation: GPS systems use distance formulas and angle calculations to plot routes.
