Trig – Sine, Cosine and Area Rules [Foundation]
The purpose of this course is to teach learners the skills they need to be able solve for unknown sides and angles in all triangles (not just right-angled triangles as learnt previously). We begin by recapping the tools learnt in Grades 9 and 10 and then progress onto the Sine Rule, Area Rule and Cos Rule to help solve for these unknowns. We finish the course by applying these tools in mixed questions, where learners need to think about which tool would be best to use.
This Foundation level course focuses on the core ideas that are important for this topic, while the Standard course will cover the same core ideas but will also include some harder questions that require more application of the core ideas.
Hope to see many of you soon in class! Mr S (:
