Webspherical law of cosines is approsimately 1 a 2 2 = (1 b 2)(1 c2 2) + bccos(A) (remember, Aneedn’t be small, just the sides!). If we multiply this out and simplify, we get a 2= b + c 2 2bccos(A) bc2=2. Since band care small, the last term is very small and can be ignored{leaving the plane law of cosines! WebThe law of cosines relates the length of each side of a triangle, function of the other sides and the angle between them. If the angle is 90° (π/2), the law of cosines becomes Pythagoras’s theorem. In a scalene triangle, knowing the length of two sides and the angle between them, we can calculate the length of the third side.
