The Birth Of Trigonometry it first appeared as the title of a book Trigonometria (literally, the measuringof triangles), published by bartholomeo pitiscus in 1595. http://www.ualr.edu/~lasmoller/trig.html
Extractions: The complex origins of trigonometry are embedded in the history of the simple word "sine," a mistranslation of an Arabic transliteration of a Sanskrit mathematical term! The complex etymology of "sine" reveals trigonometry's roots in Babylonian, Greek, Hellenistic, Indian, and Arabic mathematics and astronomy. Although trigonometry now is usually taught beginning with plane triangles, its origins lie in the world of astronomy and spherical triangles. Before the sixteenth century, astronomy was based on the notion that the earth stood at the center of a series of nested spheres. To calculate the positions of stars or planets, one needed to use concepts we now refer to as trigonometry. The earliest uses of trigonometric functions were related to the chords of a circle, and the recognition that the length of the chord subtended by a given angle x was (in modern terms) 2sin( x /2). The Greek astronomer and mathematician Hipparchus produced the first known table of chords in 140 BC. His work was further developed by astronomers Menelaus (ca. AD 100) and

Extractions: Chapter 5: Trigonometric Functions The term "trigonometry" is a combination of the two Greek terms, "trigon" and "metria", which translate as "triangle" and "measurement", and was coined by Bartholomeo Pitiscus in 1595. Thus, one might assume that "trigonometric" functions (such as, sin( x ), cos( x ), tan( x ), etc.) would be defined in terms of measurements of triangles. While this is the way they are naively defined in most High School textbooks, the earliest known calculations related to these functions were by the Greek mathematician Hipparchus in about 140 BC as measurements of circles (specifically, the lengths of chords of a circle). Thus, "trigonometric" functions are also commonly referred to as "circular" functions. While these functions do relate to measurements of both triangles and circles, from a functional point of view, the most modern perspective on these functions is actually in terms of the exponential from Chapter 3 . In 1748 (following the work of Johann Bernoulli Roger Cotes and Abraham de Moivre Euler proved the formula: e ix = cos( x i sin( x where i is the "complex" number such that
