18 May 2012 ... Share your videos with friends, family, and the world.Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical ...From the airport and airport lounge, here's what it is like to fly Singapore Airlines Airbus A350 Business Class including dining, seating, and service. We may be compensated when ...So sin(90°) is the opposite from the 90° angle in a right triangle, which is the hypotenuse, over the hypotenuse, so 1. Compare this to cosine where cosine(90°) makes no sense, because there are two “adjacent” sides. This is why I took it to be 0, because we can’t define it (this intuition came when I took my first precalc course early ...

Yes. On the unit circle, the hypotenuse is always the radius, 1. We define the sine of the angle as the y coordinate, so at 90 degrees our coordinates are (0,1) and it equals the radius 1. Thus we get sin 90 = 1 and cos 90 is the x coordinate so it is thus defined as zero.

Now let's try to find the sine of $\left(\frac\pi2 + \theta\right)$ radians, that is, the sine of $90$ degrees plus $\theta$ radians. One way to do this is, first we travel a distance $\frac\pi2$ counterclockwise from the point $(x,y)=(1,0).$ That gets us to the point $(x,y)=(0,1).$ Then we travel an additional distance $\theta$ from that point.The early data, while exciting, are far from conclusive.

Note that sina, which is defined as opposite ( h) divided by hypotenuse ( s) , equals h s in the diagram: sina = h s. Note also that the cosine of the top angle, 90− a, equals the adjacent side ( h) divided by the hypotenuse ( s ): cos(90 −a) = h s. So if sina = h s, and cos(90 −a) = h s ... Sin, cos, and tan are trigonometric ratios that relate the angles and sides of right triangles. Sin is the ratio of the opposite side to the hypotenuse, cos is the ratio of the adjacent side to the hypotenuse, and tan is the ratio of the opposite side to the adjacent side. They are often written as sin (x), cos (x), and tan (x), where x is an ...Exercise.
