The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it ...

From our ship-mast example before, the relationship between an angle and its tangent can be determined from its graph, shown below. The graphs of sine and cosine are included as well.

Graphs of Sine and Cosine 1.2 An applet illustrating how the graphs of sine and cosine are related to the unit circle. Transformations of Functions 1.3 An applet illustrating how transformations ...

Pages Sin, cos and tan Before we can use trigonometric relationships we need to understand how to correctly label a right-angled triangle.

CSS, which stands for Cascading Style Sheets, or the language that styles and arranges how page elements appear on a website, will get support for trigonometry functions such as sine, cosine ...

Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) ...

Wikimedia Next, think about the relationship between sine, cosine and the circle. Here's an illustration of the fundamental relationship between the three. Notice how the crank moves in a circle ...
