And if you plot a graph of angle against its sine, you’ll get a familiar and pleasantly curvaceous picture: The sine curve. It rises smoothly from a trough of -1, through 0, all the way to a ...

A cosine curve is graphed similarly to a sine curve, but is out of phase with it. In particular, a sine wave crosses the center line at each interval of pi (π), whereas a cosine wave peaks at ...

A graph of a functions is a visual representation of the pairs (input, output), in the plane. This applet will help you to understand the connection between the graph of a function and a function as ...

Revise trigonometric ratios of sine, cosine and tangent and calculate angles in right-angled triangles with this Bitesize GCSE Maths Edexcel guide.

With static graphs and equations, it's possible to get a handle on the rules of what various functions do and mean. ... Next, think about the relationship between sine, cosine and the circle.
