trigonometry 
By: Vicente Lopez, Deandre Williamson
who founded trigonometry ?
The first known table of chords was produced by the Greek mathematician Hipparchus in about 140 BC.
what is trigonometry? 
Trigonometry is a branch of mathematics that developed from simple mensuration (measurement of geometric quantities), geometry, and surveying. In its modern form it makes use of concepts from algebra and analysis. Initially it involved the mathematics of practical problems, such as construction and land measurement; it has since been extended to the geometry of three-dimensional spaces in the form of SPHERICAL TRIGONOMETRY.
did you know:
The complex origins of trigonometry are embedded in the history of the simple word "sine," a mistranslated 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.
how was trigonometry developed ?
The ancient Greeks transformed trigonometry into an ordered science. Astronomy was the driving force behind advancements in trigonometry. Most of the early advancements in trigonometry were in spherical trigonometry mostly because of its application to astronomy. The three main figures that we know of in the development of Greek trigonometry are Hipparchus, Menelaus, and Ptolemy. There were likely other contributors but over time their works have been loss and their names have been forgotten.
Why study Trigonometry ?
Trigonometry is used everywhere where angles and/or curves are involved. The simplest use of trig is to find missing parts of a right triangle. In this way it is used by engineers, astronomers, surveyors, and others. Trig helps to indirectly measure distances and heights. For example, a surveyor can measure width of a river or any other distance on a plane:
Jobs using trigonometry ?
Mechanical engineer, electrical engineer, civil engineer, architect, draftsman, structural engineer, pilots, navigators, astronomers, physicists, communication engineers, people working on satellites, financial analysts, pharmacist, chemist, seismologist, meteorologist, oceanographers, land surveyors, geodetic engineers, economist, computer graphics artist, game developers, optometrist and people working on optics (fiber optics for example). Trigonometry can be used as an applied mathematics or as a foundation of many branches of science and technology.
Trigonometry in Fighting?
  • One does not simply throw a punch without knowing what angle to hit from.
  • Studies have shown that when a boxer fights they create angles with their punches and foot movement.
  • A backfist is formed at a 360 degrees .

Basketball containing Trig?
  • In basketball angles and degrees are formed from shooting , passing , and movement.
  • At a free throw some of the shots will form a 30 , 50 , 70 degrees.
  • Music! As you may be aware sound travels in waves and this pattern though not as regular as a sine or cosine function, is still useful in developing computer music.
  • Trigonometry finds a perfect partner in modern architecture. The beautifully curved surfaces in steel, stone and glass would be impossible if not for the immense potential of this science
  • Digital imaging is another real life application of this marvelous science. Computer generation of complex imagery is made possible by the use of geometrical patterns that define the precise location and color of each of the infinite points on the image to be created.
  • The next time you go in for an advanced scanning procedure, be sure to check out how the sine and cosine functions you learn at school find a practical application is medical techniques such as CAT and MRI scanning, in detecting tumors and even in laser treatments.
  • Did you know that trigonometry is an arty science that can be used to measure the heights of mountains? So why would we want to measure the heights of mountains. Because this information is of great value for aircraft designing and navigation.
