The Law of Cosines - Math is Fun
the Law of Cosines (also called the Cosine Rule) says: c 2 = a 2 + b 2 − 2ab cos(C) It helps us solve some triangles. Let's see how to use it.
Cosine Rule (Laws of Cosine, Formula, Examples and Proof)
Cosine rule, in trigonometry, is used to find the sides and angles of a triangle. Cosine rule is also called law of cosine. This law says c^2 = a^2 + b^2 − 2ab cos(C). Learn to prove the rule with examples at BYJU’S.
