Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: To calculate them: Divide the length of one side by another side. Example: …

In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is …

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 …

This page includes a lesson covering 'Using the sine function to find the angle' as well as a 15-question worksheet, which is printable, editable and sendable. This is a KS3 lesson on using …

Sine, written as sin⁡ (θ), is one of the six fundamental trigonometric functions. There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles …

In order to find the sine of an angle, you must know the lengths of the opposite side and the hypotenuse. You will always be given the lengths of two sides, but if the two sides aren’t the …

How to find the Sine of an Angle? The sine of an angle α in a right-angled triangle can be represented by the ratio between the angle’s opposite side and its hypotenuse. However, you …

The sine function is defined by determining the ratio of the length of the side opposite a reference angle (acute angle) to the length of the hypotenuse of a right triangle.

In trigonometry, Sin is the shorthand of sine function. The Sine Angle Formula is, S i n θ = O p p o s i t e H y p o t e n u s e. Question 1: Calculate the sine angle of a right triangle whose …

Find the length of side x in the diagram below: The angle is 60 degrees. We are given the hypotenuse and need to find the adjacent side. This formula which connects these three is: …
