Web11.3 The Law of Cosines In Section11.2, we developed the Law of Sines (Theorem11.2) to enable us to solve triangles in the ‘Angle-Angle-Side’ (AAS), the ‘Angle-Side-Angle’ (ASA) and the ambiguous ‘Angle-Side-Side’ (ASS) cases. In this section, we develop the Law of Cosines which handles solving triangles in the WebLaw of Cosines If θ is an angle between two vectors u and v in ℝ 2 or ℝ 3, then the law of cosines says that (1) where w denotes the Euclidean norm of a vector w. This law can be used to determine the angle between two vectors. Illustration The law of cosines for two vectors in ℝ2 u = {1, 2}; v = {− 3, 4}; stfc swarm elite crew
