Sine and cosine - Wikipedia
In mathematics, sine and cosine are trigonometric functions of an angle.
Law of sines - Wikipedia
The law of sines is one of two trigonometric equations commonly applied to find lengths and angles in scalene triangles, with the other being the law of cosines. The law of sines can be generalized to higher dimensions on surfaces with constant curvature.
The Law of Sines - Math is Fun
The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle:
Law of Sines - Definition, Proof, Formula, Applications and Example
Law of sines defines the ratio of sides of a triangle and their respective sine angles are equivalent to each other. The other names of the law of sines are sine law, sine rule and sine formula. The law of sine is used to find the unknown angle or the side of an oblique triangle.
Law of Sines - Formula, Proof, Examples | Sine Rule - Cuemath
The law of sines in Trigonometry can be given as, a/sinA = b/sinB = c/sinC, where, a, b, c are the lengths of the sides of the triangle and A, B, and C are their respective opposite angles of the triangle.

Chapter 3: Laws of Sines and Cosines - Mathematics LibreTexts
The laws of sines and cosines were first stated in this context, in a slightly different form than the laws for plane trigonometry. On a sphere, a great-circle lies in a plane passing through the sphere’s center. It gives the shortest distance between any two points on a sphere, and is the analogue of a straight line on a plane.
The law of sines, including the ambiguous case. - themathpage
The law of sines is a theorem about the geometry of any triangle. As any theorem of geometry, it can be enunciated. The algebraic statement of the law --
4.1: The Law of Sines - Mathematics LibreTexts
The Law of sines is based on right triangle relationships that can be created with the height of a triangle. Often, in this type of a problem, the angles are labeled with capital letters and their corresponding sides are labeled with lower case letters.
