## How To Use Cosine Rule

31/05/2009 · and sine and cosine rule are not needed if you can use SohCahToa, that's why they are used for other triangles than the right angled ones /edit/ well i bet u know how to use sine and cosine rule? so basically, if you are not sure which one to use, try the sine rule (it's shorter and easier), if it's not working with the question, the cosine rule will work.
