In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles. According to the law, The law of sines is one of two trigonometric equations commonly applied to find lengths and angles in scalene triangles, … See more According to Ubiratàn D'Ambrosio and Helaine Selin, the spherical law of sines was discovered in the 10th century. It is variously attributed to Abu-Mahmud Khojandi, Abu al-Wafa' Buzjani, Nasir al-Din al-Tusi See more The following are examples of how to solve a problem using the law of sines. Example 1 Given: side a = 20, … See more The spherical law of sines deals with triangles on a sphere, whose sides are arcs of great circles. Suppose the radius of the sphere is 1. Let a, b, and c be the lengths of the great-arcs that are the sides of the triangle. Because it is a unit sphere, … See more The area T of any triangle can be written as one half of its base times its height. Selecting one side of the triangle as the base, the height of … See more When using the law of sines to find a side of a triangle, an ambiguous case occurs when two separate triangles can be constructed from the data provided (i.e., there are two different possible solutions to the triangle). In the case shown below they are triangles … See more In hyperbolic geometry when the curvature is −1, the law of sines becomes In the special case when B is a right angle, one gets See more Define a generalized sine function, depending also on a real parameter K: The law of sines in constant curvature K reads as By substituting K = 0, K = 1, and K = −1, one obtains respectively the Euclidean, spherical, and … See more

WebWhen you write and solve the law of sines, you end up with sinC=0.32 or something. You type sin^-1 (0.32) in your calculator and you are given an acute angle. Actually there are two solutions to the equation sinC=0.32. One is acute (your calculator gave it to you) and the other solution is obtuse. WebSummary of the law of sines The law of sines is expressed as follows: where, a, b, c represent the lengths of the sides of the triangle and A, B, C represent the angles of the triangle. The sides are denoted using lower … balli di gruppo bambini youtube
