In this lesson, we break down the step-by-step proof for one of the most fundamental identities in trigonometry: sin² x + cos² x = 1.Understanding where this identity comes from is essential for mastering more complex trigonometric proofs and equations in Grade 11 and 12. We use a right-angled triangle and the Pythagorean theorem to show how this identity is derived.
What you will learn:The relationship between sine, cosine, and the sides of a right-angled triangle.How to apply the Theorem of Pythagoras in a coordinate system.The algebraic steps to simplify and reach the final identity.
Perfect for South African Grade 11 and 12 learners following the NSC or IEB curriculum.
