Trigonometry: Sine, Cosine and Area Rules

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. We begin by recapping the tools learnt in Grades 9 and 10 and then progress on to the Area Rule, Sine Rule and Cos Rule to help solve for these unknowns. We finish the course by applying these tools in mixed questions involving triangles, where learners need to think about which tool would be best to use.

This course takes the basics one step further to provide some extended examples and questions for those learners who enjoy a challenge. It will move at a quicker pace and cover questions of greater complexity.
