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.

This applet shows how the graphs of sin (θ) and cos (θ) follow directly from the definition of these functions. Move the slider to change the angle. Observe that after the point moves once around the ...

Learn and revise trigonometric ratios of sine, cosine and tangent and calculate angles and lengths in right-angled triangles with GCSE Bitesize AQA Maths.

Working with the graphs of trigonometric functions Trigonometric graphs Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points.

The tangent can be determined with a collection of mathematical formulas but is most commonly determined by dividing the sine function by the cosine function.

In high school, you probably learned that trigonometric functions – like sine, cosine and tangent –can be derived, geometrically, from a circle (hence why trig functions are also known as ...

Well, there's a GIF for that: Wikimedia Next, think about the relationship between sine, cosine and the circle. Here's an illustration of the fundamental relationship between the three.
