TRIGONOMETRY IN EASY WAY
Today is the time of Scientific Discoveries in which in Science field, technology
field and so many others
...
The fundamental trigonometric functions
like sine and cosine are used to describe the sound and light waves
...

Trigonometry, the branch of mathematics concerned with specific functions of
angles and their application to calculations
...
The field emerged in the Hellenistic world during the 3rd
century BC from applications of geometry to astronomical studies
Trigonometry is a study of the relationship of angles, lengths, and heights
...
Now it has spread its application into wider fields like
engineering, physics, surveyors, architects, astronauts and even in the
investigation of a crime scene
...
C
...
Hipparchus also developed the first accurate star
map
...
"

Hipparchus was the first to tabulate the corresponding values of arc and chord for
a series of angles
...
You may find it helpful to remember
Sine, Cosine and Tangent as SOH CAH TOA
...

Mainly there are three functions use in trigonometry
...
Sine (Sin)
2
...
Tangent (tan)
And the other three functions are derived or based from above three functions
...
Cotangent (Cot)
2
...
Cosecant (Cosec)
Trigonometric identities are used in our real life like finding the sine of an angle
will help when determining how much of a certain material is needed to use in
order to construct the building
...

Trigonometry plays a major role play in our business industry, where it allows
manufacturers to create everything from automobiles to zigzag scissors
...

Trigonometry is used to in measuring the height of a building or a mountain
...


Euclid (who lived around 300 BC) made heavy use of chords of circles, which are
completely equivalent to sines of angles
...
The first person whose name we
know who worked with sines was Aryabhata, who lived around AD 500
...
In Electrical Engineering, Calculus
(Integration) is used to determine the exact length of power cable needed to
connect two substations, which are miles away from each other
...
People can use panels in rooms such as studios and turn them in different
angles so that the music waves bounce off just right to make the song sound
smooth and even
