The law of sine and cosine
Splet14. mar. 2024 · Cosine Rule. The cosine rule provides a relationship between the lengths of the sides a triangle to the cosine of its opposite angles. Just as is in the image, the cosine rule relates the length, a to its opposite angle, A. a² = b² + c² – 2bc . cos(A°) b² = a² + c² – 2ac . cos(B°) c² = a² + b² – 2ab . cos(C°) Applications of ...
