This video is a tutorial on Sine and Cosine Rule. Please make yourself a revision card while watching this and attempt my examples. Straight away then move to my video on Sine and Cosine Rule 2 - Exam Questions 18. This video is for students attempting the Higher paper AQA Unit 3 Maths GCSE, who have previously sat the foundation paper. Explanations are aimed at being as simple as possible and so students who previously did the Foundation paper can access. They would also be useful for students who have always sat the higher paper. www.hegartymaths.com www.hegartymath...

The only problem for some students is remembering it afterwards [along with all the other parts of a maths syllabus], plus another 5 or 6 subjects which need to be mastered for exams.

Right angled triangle then either Pythagoras or SoHCaHToA. If have two sides and finding the other then Pythag. If one side and one angle to find a side or two sides to find and angle then SoHCaHToA. If non right angled use Cosine or Sine Rule. If you ever see a side and an angle opposite use the sine rule - otherwise use Cosine Rule (i.e. if have three sides and no angle or two sides with angle between). Hope helps. Good luck revising!

I must say, if I pass my exams and get an A (as this is what I need for further Maths at A Level) I will have to find you and give you a million pounds. You are the most helpful revision channel I have ever seen. Keep up the excellent work! :)

After not thinking maths was serious, I did quite bad on my Unit 1 and 2, then I found these videos. My exam is tomorrow and nearly covered them all. I want to take a level maths, but I have to get a High B to do that. To get my B I have to get an A. and I'm rubbished at maths. Thanks so much for helping.

Dear Ellie, Thank you so much for taking the time to send me your kind words and if I have helped you in a small way then I am delighted. You can still do well so keep going but then get a decent night's sleep. Wishing you all the best. Mr H!
