2 A level Maths Trigonometry Compound Angle Formulae
About this lesson
In this A-level trigonometry video, we delve into the essential compound angle formulae. You'll learn how to state the formulae for sine and cosine of sums and differences of angles. We'll explore how the odd and even properties of sine and cosine functions allow us to derive new expressions. This video will equip you to understand and derive formulae for sine, cosine, and tangent of A plus B and A minus B. Subscribe to @AxiomTutoringCourses for more A-level math tutorials.
