Theorem 1.1 (The Spherical Law of Cosines): Consider a spherical triangle with sides α, β, and γ, and angle Γ opposite γ. To compute γ, we have the formula Proof: Projectthe triangle ontothe plane tangentto the sphere at Γ and compute the length of the projection of γ in two different ways.
WebThe Law of Sines can be written either way! You can put the angles in the numerators and the sides in the denominators, or the other way around. To understand why, think about this true equation: 1/2 = 2/4 = 3/6 It's still true if we reverse the numerators and denominators: … The law of tangents can be used to compute the missing side and angles of a triangle in which two sides a and b and the enclosed angle γ are given. From $${\displaystyle \tan {\tfrac {1}{2}}(\alpha -\beta )={\frac {a-b}{a+b}}\tan {\tfrac {1}{2}}(\alpha +\beta )={\frac {a-b}{a+b}}\cot {\tfrac {1}{2}}\gamma }$$ one can … See more In trigonometry, the law of tangents is a statement about the relationship between the tangents of two angles of a triangle and the lengths of the opposing sides.
