The ONLY Trigonometry Video YOU NEED at GCSE Maths | Achieve a Grade 9

The Only Trigonometry Video YOU Will Need at GCSE Maths | Achieve a Grade 9 | SOH CAH TOA This video aims to provide the ultimate guide for both Foundation and Higher students. I split the video into right angle trig, and non-right angle trig. Trigonometry is such an important and often misunderstood topic at GCSE Maths so I believe this video has lots of value to add! In the right angle trig: I include basic instructions of exactly what trigonometry does, how to calculate lengths of sides and sizes of angles using SOH CAH TOA. In the non-right angle trig: I explore rules such as the sine and cosine rules, as well as the best way to calculate the area of a triangle when it isn't as simple as just 0.5*b*h! Both sections end with an exam style question for practice too! As always let me know if you have any questions, but I hope this video helps! ---------------------------------- CHAPTERS: 0:00 - What is Trigonometry 1:11 - Right Angle Trigonometry (Grade 4-7) 9:17 - Exam Question 1 13:25 - Non Right Angle Trigonometry (Grade 6-9) 21:06 - Sine vs Cosine Rules 22:20 - Exam Question 2 ---------------------------------- MY NEW WEBSITE! https://brainstormmaths.com
