Division of sines
WebA lot of questions will ask you the arcsin (4/9) or something for example and that would be quite difficult to memorize (near impossible). So it just depends on the question. 5) Yes, absolutely correct. arcsin (1/2) = pi/6 for example. Pi/6 … WebNov 17, 2024 · Theorem 2.1.1: Law of Sines If a triangle has sides of lengths a, b, and c opposite the angles A, B, and C, respectively, then a sinA = b sinB = c sin C . Note that by taking reciprocals, Equation 2.1.1 can be written as sinA a = sinB b = sinC c , and it can also be written as a collection of three equations:

WebFeb 13, 2024 · Earlier, you were asked how an equation changes when a sine or cosine graph is stretched by a factor of 3 . If a sine graph is horizontally stretched by a factor of 3 then the general equation has \(b=\frac{1}{3}\). This is because \(b\) is the frequency and counts the number (or fraction) of a period that fits in a normal period of \(2 \pi\). Web1 The sine and cosine as coordinates of the unit circle The subject of trigonometry is often motivated by facts about triangles, but it is best understood in terms of another geometrical construction, the unit circle.
