WebTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. WebThe ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle A A below: In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides.

WebMay 28, 2024 · The basic sine and cosine functions have a period of 2\pi. The function \sin x is odd, so its graph is symmetric about the origin. The function \cos x is even, so its graph is symmetric about the y -axis. The graph of a sinusoidal function has the same general shape as a sine or cosine function. WebMay 9, 2024 · Figure 7.6.3: y = − 3sin(2x + π 2) involves sine, so we use the form y = Asin(Bt − C) + D Amplitude is A , so the amplitude is − 3 = 3. Since A is negative, the graph is reflected over the x -axis. Period is 2 π B ,so the period is 2π B = 2π 2 = π The graph is shifted to the left by C B = π 2 2 = π 4 units.
