We use sin, cos, and tan to solve many real-life problems. Here is an example to understand the applications of sin, cos and tan. Example: A ladder leans against a brick wall making an angle of 50 o with the horizontal.

Sine Definition. The sine of an angle can be defined as the ratio of the length of the perpendicular to the length of the hypotenuse in a right-angled triangle. It gives the value of the sine function of the angle between the base and hypotenuse of the right triangle.
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.
Sine, Cosine and Tangent. 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.)

The sine function, commonly denoted as sin (x), is a mathematical function that associates each angle x with the value of the ratio of the length of the opposite side to the length of the hypotenuse in a right-angled triangle.
