Law of cosines also known as cosine rule or cosine law, helps to find the length of the unknown sides of a triangle when other two sides and angle between them is given. Learn formulas at BYJU’S.
The Law of Tangents Most geometry and pre-calculus books have entire units devoted to learning about two of the most important formulas in mathematics: the law of sines and the law of cosines. Both of these are very useful and very powerful tools, as they can be used to find unknown ang...
