In this video we take a look at cosine rule and how to use it. When there is an included angle and two lengths, this rule can be used to calculate the other missing length. On the other hand, when all lengths are given, any angle can be calculated using cosine rule.
In this video we also go through challenges students usually have with cosine rule, which would help you to be more prepared for questions. This video also briefly looks at the angle of elevation and depression too.
