4. The law of cosines, or cosine rule, connects the length of an unknown side of a triangle to the length of the other sides and the angle opposite to the unknown side.
5. Often, once you've found theorems for a specific subclass you can try and generalise them, but often the generalised form isn't as elegant ( compare Pythag to the cosine rule ).
6. It's difficult to find cosine rule in a sentence. 用cosine rule造句挺難的
7. Once you have got these right triangles you can apply the Pythogorean theorem, perform some trigonometric calculations to obtain the identity given by the cosine rule ( try it for an equilateral triangle by dividing the triangle into two right triangles of equal area.
8.
