	Trigonometry Encyclopedia
		Trigonometry specifically deals with the relationships between the sides and the angles of triangles, that is, the trigonometric functions, and with calculations based on these functions.
		Trigonometry has important applications in many branches of pure mathematics as well as of applied mathematics and, consequently, much of science.
		Trigonometry is usually taught in secondary schools, often in a precalculus course.

	Trigonometry - Wikipedia, the free encyclopedia
		Trigonometry (from the Greek trigonon = three angles and metro = measure) is a branch of mathematics dealing with angles, triangles and trigonometric functions such as sine, cosine and tangent.
		The origins of trigonometry can be traced to the civilizations of ancient Egypt, Mesopotamia and the Indus Valley, more than 4000 years ago.
		The earliest use of sine appears in the Sulba Sutras written in India between 800 BC and 500 BC, which correctly computes the sine of π/4 (45°) as 1/√2 in a procedure for circling the square (the opposite of squaring the circle).

	Trigonometric function
		The trigonometric functions, as the name suggests, are of crucial importance in trigonometry, mainly because of the following two results: The law of sines for an arbitrary triangle states:\n:\nIt can be proven by dividing the triangle into two right ones and using the above definition of sine.
		The next significant development of trigonometry was in India, in the works known as the Siddhantas (4th–5th century), which first defined the sine as the modern relationship between half an angle and half a chord.
		All of these earlier works on trigonometry treated it mainly as an adjunct to astronomy; perhaps the first treatment as a subject in its own right was by the De triangulis omnimodus (1464) of Regiomontanus (1436–1476), as well as his later Tabulae directionum (which included the tangent function, unnamed).
