Trigonometry finds its applications in various important fields that make our life easier. We have prepared a list of Applications of Trigonometry in Life.

1. Applications of Trigonometry in Real Life
Trigonometry is the science of making calculations with triangles. It is used
to measure the sides, lengths, heights and angles of triangles.
It was first endorsed in the 3rd century to facilitate astronomical purposes
including navigation and the creating calendars. Even today, Trigonometry
plays a vital role in calculating distance between celestial bodies.
Often in school when you’re troubled with the trigonometry problems, you
ask yourself, “Will I ever use Trigonometry in real life?” Well, we may not
use Trigonometry directly, but it does benefit us in other ways.
Trigonometry finds its applications in various important fields that make
our life easier.

Trigonometry and Music
Do you enjoy listening to music? Your answer is probably yes. You have
Trigonometry to thank for it! Trigonometry plays a vital role in the
production of music. It is used in measuring the pitch of sound waves to
create the musical notes.
Sound engineers utilize the basics of trigonometry in order to represent
music through the computer. The computer uses graphical representation
of music in order to develop and understand it.
Trigonometry also plays a key role in the placement of the speakers. The
sound engineers utilize trigonometry to control the volume and pitch of
sounds as they have a great impact on the quality of music.

3. Trigonometry and Video Games
Who doesn’t love playing video games? Most of us spent our childhood
playing video games like Mario, Sonic, Pac -Man, Snow Bros, etc. Have you
ever wondered how your favorite video game superhero jumps, runs or
kicks?
Take a guess!
*Drum rolls* Correct! It is through trigonometry.
All your favorite video games are created by utilizing the basics of
trigonometry as they are created on the computer. He nce, game developers
are highly dependent on trigonometry.
Trigonometry and Architecture
We’re no magicians but we’re assuming that you live in a house or an
apartment. We got it right, didn’t we?
Did you know that architects use trigonometry to design and create
buildings? Trigonometry is essential in constructing houses and buildings.

4. Here’s why:
• Trigonometry helps architects create walls perpendicular or
parallel.
• It is used to measure plot or area.
• It is used to install tiles.
• It is also used to calculate the roof pitch and slope.
• Trigonometry also helps in calculating the structural loa d.
• It is used to calculate sun shading.
• It is also essential in calculating the light angles.
Trigonometry and Navigation
Trigonometry sets you in the right direction!
No, seriously.
Trigonometry plays an important role in navigation. It is used to po int you
in the right direction. Compass utilizes the rules of trigonometry to show
us the right direction. Trigonometry helps us locate the horizon. It also
helps us measure the distance between the shore and a point in the sea.

5. Trigonometry and Marine Biology
Marine Biologists employ trigonometry to make measurements under sea.
Trigonometry helps Marine Biologists:
• It helps them find out how the sunlight affects the ability of algae to
photosynthesize at different levels of depth under sea.
• Trigonometry is essential for marine biologists in order to calculate
the sizes of sea animals from a far.
• Marine biologists employ trigonometry to observe and understand
the behaviors and characteristics of different wild sea animals.
Trigonometry and Manufacturing Industry
Trigonometry plays an essential role in the manufacturing industries
like:
• Automotive Industry
• Clothing Industry
• Aviation Industry

6. • Cartography Industry
• Construction Industry
The basics of trigonometry are used in producing heavy vehicles or
automobiles to kitchenware. Automotive industries rely on the rules of
trigonometry to measure the angles and sizes o f the parts used in the
manufacture of the vehicles and machinery.
Basic trigonometry skills are also used by smaller industries like clothing
industries to design and measure the lengths of cloth.
Trigonometry and Flight Engineering
Trigonometry is an essential component in Flight Engineering. Flight
Engineers are required to pay more attention to trigonometric basics in
order to measure the effects of wind on the plane.
Wind determines the course of your plane and the speed at which the plane
will arrive at its destination. Hence, flight engineers have to take care of
the speed, direction and intensity of the wind along with the speed,
distance and direction of their plane.
Trigonometry and Physics
Physics is heavily dependent on trigonometry for its calculations and
measurements.
Physics utilizes the rules of trigonometry:
• To model the mechanics of oscillations.
• To design the mechanics of physical and electromagnetic waves.
• To find the components of vectors.
• To utilize dot and cross products.

7. • To calculate the strength of fields.
• In projectile motion as well.
Trigonometry and Criminology
Did you know that trigonometry also helps us catch criminals? Trigonometry
even finds its applications in a field as exciting as Criminology. Detectives
and criminologists utilize trigonometric principles to uncover criminal
activities.
Criminologists employ trigonometry in ord er to:
• Calculate the distance from where the bullet must have been shot.
• Detect what must have caused a car accident.
• To calculate the intensity of the collision of two cars.
• Calculate the height of a fallen object.
• Calculate the angle of criminal attack.
Trigonometry and Archeologists

8. Could you believe that trigonometric principles helped us discover
dinosaurs? Trigonometry is employed to divide the excavation sites into
equal parts. Archeologists use excavation tools which require some
understanding of trigonometric principles.
Archaeologists also utilize the rules of trigonometry to calculate the
underground water levels.
Trigonometry and Marine Engineering
Marine Engineers utilize the principles of trigonometry to create and
navigate marine vessels such as the Marine ramp. A mari ne ramp is a slope
or a staircase that connects the lower and higher levels of areas.
Well that’s a wrap on our list of applications of trigonometry in real life.
Did your perception of trigonometry change after learning all these cool
facts? Do you have anything cooler to add?
