cosine rule for side

cosine rule for side Cosine rule is also called law of cosines or Cosine Formula Suppose a b and c are lengths of the side of a triangle ABC then a2 b2 c2 2bc cos x b2 a2 c2 2ac cos y c2 a2 b2 2ab cos z where x y and z

The cosine rule is a 2 b 2 c 2 2bcCosA Use this formula when given the sizes of two sides and its included angle Example Find the length of BC Answer We have Solving for a side with the law of cosines Learn how to use the law of cosines to find the missing side length of a triangle when given two side lengths and the contained angle measure Created by Sal Khan

The cosine rule also known as the law of cosines relates all 3 sides of a triangle with an angle of a triangle It is most useful for solving for missing information in a triangle For example if all three sides of the triangle are known the cosine rule allows one to find any of the angle measures Statement The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them
