Trigonometry + trigonometric equations
In this course you'll start by looking in depth at the sine and cosine rules for the area of a triangle. You'll think carefully about how to extent the definitions of sin cos and tan to angles of any size and to solve. You'll learn about some exact forms for these ratios and be confident in solving equations using sin cos and tan. This will including quadratics in these functions and problems where you have to apply trigonometric identities before solving the equation.
Worksheets with full video solutions will guide you through problems of a range of difficulties, including routine examples to get the hang of the basics as well as some very tough challenge style problems that will stretch you to fully master the ideas.
