Trigonometric functions of negative angles
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. WebIf for real values of x, cosθ = x + 1 x, then ______.

Let's start with the easier first part. The most important angles are those that you'll use all the time: 30 ° = π / 6 30\degree = \pi/6 30° = π /6; 45 ° = π / 4 45 ... WebMar 26, 2016 · First, consider the –45-degree angle. This angle has its terminal side in the fourth quadrant, so its sine is negative. A 45-degree angle, on the other hand, has a positive sine, so. In plain English, the sine of a negative angle is the opposite value of that of the positive angle with the same measure. Now on to the cosine function.
