How To Do Law Of Cosines The law of cosines or cosine rule is a formula that can be used to calculate a missing side or missing angle in a triangle To apply the law of cosines you need to know the correct
The law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles Cosine law in trigonometry generalizes the Pythagoras theorem Understand the cosine rule The Law of Cosines also called Cosine Rule or Cosine Law states that the square of a side of a triangle is equal to the sum of the squares of the other two sides minus twice their product
