What will I learn?
This Trigonometry Course builds strong skills in unit circle ideas, exact values, and main identities, while stressing clear, strict problem-solving. You will practise organised solutions, proof writing, and exact reporting, then apply periodic functions, angular speed, and sinusoidal models to real data, learning to interpret parameters and present accurate, well-supported results quickly.
