Rule of sines
WebbThe Sine Rule, also known as the law of sines, is exceptionally helpful when it comes to investigating the properties of a triangle. While the three trigonometric ratios, sine, cosine and tangent, can help you a lot with right angled... 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, with the other being the law of cosi…

Webbwww.brilliantmaths,com WebbIn order to see why these laws are valid, we’ll have to look at three cases. For case 1, we’ll take the angle C to be obtuse. In case 2, angle C will be a right angle. In case 3, angle C will be acute. Case 1. For this case, we take angle C to be obtuse. This case has a wrinkle in it since the cosine of an obtuse angle is negative.
