Trigonometry is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides.

The first trigonometric table was apparently compiled by Hipparchus,

who is now consequently known as "

the father of trigonometry.

WHAT IS TRIGNOMETRY?

SINθx=adjacent/hypotenuse

COSθx=opposite/hypotenuse

TANθx=opposite/adjacent

COTθx=1/TANθx

COSECθx=1/SINxθ

SECxθ=1/COSxθ

TRIGNOMETRY FUNCTIONS

In 2001, a group of European astronomers did an experiment that started in 1997 about the distance of Venus from the Sun.

The Sun, The Earth, and Venus makes a triangle because the Sun is stationary and the Venus rotates opposite of the Earth.

With the Earth rotating 15 degrees every hour, it was possible to find the angle of Venus to the Earth and the Sun to the Earth.

This research lasted for four years to get accurate measurement. By the time they got All the measurement, they calculate the that Venus was about 105,000,000 kilometers away from the Sun and the Earth was about 150,000,000 kilometers away.

**A rocket tracking facility has two radar stations the rocket continuously transmit the angles of elevation to a computer in space station in earth Finding the distance to the rocket from at the sattlite are known by using trignometry**

**Distance from a Rocket to a Radar Station**

By using trignometric functon

cos 30= 4625/x

4625/0.865=x

X=5346.820km

Distance from rocket to space station=5346.820

Distance from space station on earth to satellite is 4625 kms and it is making angle of 30 degrees to the rocket

X=distance from rocket to space station

**There are an enormous number of uses of trigonometry**

USES IN SPORTS

In Cricket

in soccer ,etc

IN CRICKET trigonometry

is used

(HAWK EYE TECHNOLOGY)

for tracking the path of the ball . The computer reads in the video in time, and tracks trealhe path using its speed and angle of deviation

Use in cricket

Trigonometry is commonly used in finding the height of towers and mountains.

It is used in navigation to find the distance of the shore from a point in the sea.It is used in oceanography in calculating the height of tides in oceans

Use in daily life

Use in daily life

conclusion

WHERE EVER YOU GO TRIGNOMETRY WILL BE THERE

Not only uses which we had said there are an enormous number of uses of trigonometry
