What will I learn?

You will develop a complete, working knowledge of the cosine function across eight core areas of mathematics and its applications. Starting from the unit circle and right-triangle definitions, you will progress through transformations, inverse functions, and trigonometric identities. The course then moves into calculus, covering derivatives, integrals, and optimisation problems involving cosine. You will also explore cosine in vectors, complex numbers, and Fourier series. Supplementary material connects these concepts to data science, AC circuits, structural mechanics, and signal processing.
