4 A level Maths Trigonometry Proving Trig Identities

In this A-level trigonometry video, we delve into the crucial skill of proving trigonometric identities. You'll learn how to strategically use known identities to manipulate and simplify expressions, transforming one side of an identity to match the other. We'll cover the proper use of equivalence notation and demonstrate working through examples, starting with a fundamental identity involving secant squared and then tackling a more complex triple angle identity.
