Trigonometric functions - Wikipedia, the free encyclopedia

In mathematics, the trigonometric functions (also called circular functions) are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. Tr...

Since Q(x,y) is a point on the unit circle, we know that . This fact and the definitions of the trigonometric functions give rise to the following fundamental identities:

The hyperbolic functions enjoy properties similar to the trigonometric functions; their definitions, though, are much more straightforward: ... While , , parametrizes the unit circle, the hyperbolic functions , , parametrize the standard hyperbola , x>1.

You may already be familiar with some functions, maybe the linear and quadratic power functions, for instance. This notebook is about another set of functions, the trigonometric functions. They are often called the trig functions for short.

As long as we're doing that, we should also define the trig functions for angles beyond 180° and for negative angles. First we need to be clear about what such angles are.

It is helpful if the user already knows some elementary facts about the trigonometric functions. (See e.g. the applet Definition of the trig functions). If appropriate, the Tangens function may be ignored. The applet is started from the red button in its own window.
