In this Powerpoint lesson students are shown ways to prove the cosine rule and then using the cosine rule and other trig formulae answer the exam questions they encounter on this topic. All questions are provided with answers.

This is the last lesson in the series of lessons on all non-right angled traingle trigonometry. Students are presented with problems where they have to apply multiple trig rules they’ve learned over the last few lessons (area rule, sine rule, cosine rule) in order to solve multistep problems. All answers are provided on the slides

This is a complete unit of More trigonometry (Non-right angled triangle trigonometry) topic at GCSE level. It comprises of 12 lessons. all with worked examples, and solutions provided on the slides. some of the lessons come with additional worksheets for extra parctise.
