Trigonometry And Pythagoras' Theorem
Akopọ
Trigonometry connects angles to lengths, making it possible to calculate distances that are impossible to measure directly. Combined with Pythagoras' theorem, it forms the backbone of geometry questions across both Edexcel papers.
You will master Pythagoras' theorem for right-angled triangles, use sine, cosine and tangent ratios to find unknown sides and angles, and at Higher tier extend these ideas to any triangle using the sine rule, cosine rule and the area formula.
