Trigonometry - 4. Sine and Cosine Rules

A few years ago I wrote a set of notes for students and put them on my website. The notes were supposed to be written in a “student-friendly” way, and different to notes students might find in textbooks or elsewhere on the internet. I have converted the notes to PowerPoint slides so you can download them, adapt them if needed, use them in revision lessons or perhaps give your students a set to take home with them to help them prepare for exams. The chances are there will be a few mistakes here and there, so if you spot any please email me & I will correct them. Hope they are of use!
