Homework 8 law of cosines.

Derive cos (A-B) from the law of cosines. In summary, the answer to this question is that the cosine rule is used to solve a equation that is similar to the equation for the hypotenuse of a right triangle.f.But from the equation c sin B = b sin C, we can easily get the law of sines: The law of cosines. There are two other versions of the law of cosines, a 2 = b 2 + c 2 - 2bc cos A and b 2 = a 2 + c 2 - 2ac cos B. Since the three verions differ only in the labelling of the triangle, it is enough to verify one just one of them.Math. Trigonometry. Trigonometry questions and answers. 1.
