Hipparchus is the father of trigonometry.
Technically, no. However, there a great number of things that would be impossible without at least a basic grasp of trigonometry, and even more that are only possible with an understanding of increasingly advanced concepts.
trigonometry is very imr
Yes, you would need Pythagoras and trigonometry.
Trigonometry is used in the design and construction of buildings, cars, planes, and many other objects. Trigonometry is used in physics and engineering whenever forces, waves, fields, and vectors are involved. Trigonometry is used in music and acoustics to design speakers, instruments, and concert halls. Trigonometry is used to coordinate launches OS space shuttles. Trigonometry is used to navigate ships and planes. Nearly every part of modern life uses trigonometry in some way.
It's good for robotics and computers. If you're good at trigonometry then you can figure out the navigation.

The word trigonometry originates from the two Greek words 'trigon' and 'metron'. While 'trigon' has the meaning of triangle, 'metron' means to measure. The literal translation of the word trigonometry is to measure triangles.
It depends on what the school prefers. I would think that 9th graders in a school for kids with learning disabilities normally learn Pre-Algebra, or Algebra 1. For a 9th grade class in a mainstream school, I would think that most 9th graders would learn Algebra 1, Geometry, Algebra 2, or Trigonometry. I would think that Trigonometry is mostly for gifted 9th graders.

No. I have worked as a Graphic Designer for over 20 years both in Europe an the USA and have never had to use trigonometry.
History of trigonometry.The history of trigonometry dates back to the early ages of Egypt and Babylon. Angles were then measured in degrees. History of trigonometry was then advanced by the Greek astronomer Hipparchus who compiled a trigonometry table that measured the length of the chord subtending the various angles in a circle of a fixed radius r. This was done in increasing degrees of 71.In the 5th century, Ptolemy took this further by creating the table of chords with increasing 1 degree. This was known as Menelaus's theorem which formed the foundation of trigonometry studies for the next 3 centuries. Around the same period, Indian mathematicians created the trigonometry system based on the sine function instead of the chords. Note that this was not seen to be ratio but rather the opposite of the angle in a right angle of fixed hypotenuse. The history of trigonometry also included Muslim astronomers who compiled both the studies of the Greeks and Indians.In the 13th century, the Germans fathered modern trigonometry by defining trigonometry functions as ratios rather than lengths of lines. After the discovery of logarithms by the Swedish astronomer, the history of trigonometry took another bold step with Isaac Newton. He founded differential and integral calculus. Euler used complex numbers to explain trigonometry functions and this is seen in the formation of the Euler's formula.The history of trigonometry came about mainly due to the purposes of time keeping and astronomy.
