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).

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 angle in radians or degrees. Created by Sal Khan.
As we know, tan is the ratio of sin and cos, such as tan θ = sin θ/cos θ. Thus, we can get the values of tan ratio for the specific angles. Sin Values. sin 0° = √(0/4) = 0. sin 30° = √(1/4) = ½. sin 45° = √(2/4) = 1/√2. sin 60° = √3/4 = √3/2. sin 90° = √(4/4) = 1. Cos Values. cos 0° = √(4/4) = 1. cos 30° = √(3/4
Trigonometry. Sin, Cos and Tan A-Level Maths, Quadrants and the "cast" Rule. On a set of axes, angles are measured anti-clockwise from the positive x-axis. So 30° would be drawn as follows: The angles which lie between 0° and 90° are said to lie in the first quadrant.
Sine, Cosine and Tangent are all based on a Right-Angled Triangle. They are very similar functions so we will look at the Sine Function and then Inverse Sine to learn what it is all about. Sine Function. The Sine of angle θ is: length of the side Opposite. divided by the length of the Hypotenuse. Or more simply: sin ( θ) = Opposite / Hypotenuse

Plane Trigonometry. Spherical Trigonometry. In this article, let us discuss the six important trigonometric functions, ratios, trigonometry table, formulas and identities which helps to find the missing angles or sides of a right triangle. Trigonometry Ratios-Sine, Cosine, Tangent.
Solution: In the triangle, the longest side (or) the side opposite to the right angle is the hypotenuse. The side opposite to θ is the opposite side or perpendicular. The side adjacent to θ is the adjacent side or base. Now we find sin θ, cos θ, and tan θ using the above formulas: sin θ = Opposite/Hypotenuse = 3/5.
This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle. The Sine, Cosine and Tangent functions express the ratios of sides of a right triangle.
