Watch on. The Graphs of Sin, Cos and Tan - (HIGHER TIER) The following graphs show the value of sinø, cosø and tanø against ø (ø represents an angle). From the sin graph we can see that sinø = 0 when ø = 0 degrees, 180 degrees and 360 degrees. Introduction to the trigonometric ratios. Trigonometric ratios in right triangles. Learn how to find the sine, cosine, and tangent of angles in right triangles. The 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). The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a right-angled triangle divided by another. For any angle " θ ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.) Laws of sines and cosines review. Google Classroom. Review the law of sines and the law of cosines, and use them to solve problems with any triangle. Law of sines. a sin ( α) = b sin ( β) = c sin ( γ) Law of cosines. c 2 = a 2 + b 2 − 2 a b cos ( γ) Want to learn more about the law of sines? Check out this video. Generalized trigonometry.
