10 Real Life Trigonometric Applications: What No One Is Talking About

Trigonometry is also extremely useful in everyday life. In this blog, we’ll look at some of the Trigonometric Applications in our daily lives.

Trigonometry is one of the most used math disciplines in our day-to-day lives. We use it in architecture, science, medicine, aviation, and others, the only thing is that we are unaware of its applications and its uses.

What is Trigonometry?

Trigonometry Applications

The word Trigonometry is originated from the Greek word, Τριγωνoμετρία, which means three  +  angles  +  to measure. Trigonometry is a discipline of mathematics concerned with triangles, particularly triangles with a single 90-degree angle known as the right triangle.

The origins of trigonometry can be traced back over 4000 years to ancient Egypt, Mesopotamia, and the Indus Valley civilizations (India). Astronomy was the first trigonometry application, it was created as a navigation strategy for sailors.

10 Trigonometry Applications in Real Life

Trigonometry is an essential topic in mathematics that is taught to high school students in their math class as part of their curriculum. Trigonometry is also extremely useful in everyday life. In this blog, we’ll look at some of the Trigonometry applications in our daily lives.

1. Video Games

Video Games

Have you noticed cartoon characters gliding smoothly over all the obstacles? Do you think the cartoon jumps and glides?

The cartoon doesn’t actually jump straight along the Y-axis; instead, it follows a slightly curved or parabolic path to avoid the obstructions in its path. The cartoon can leap over these barriers with the help of trigonometry applications.

2. Architecture

As we know, in trigonometry, the height of a structure can readily be determined using the distance from where you perceive it and the angle of elevation; similarly, with help of Trigonometry, we can determine the height of monuments, statues, and mountains, and other high rise structures.  

Measuring fields, constructing parallel and perpendicular walls, and putting up ceramic tiles are a few other examples where trigonometry is required in architecture. 

3. Aviation

In the previous few years, aviation technology has advanced significantly. Pilots have to consider the aircraft’s speed, distance, and direction, as well as the wind’s speed and direction. For example, if a plane is flying at a particular speed in a north-east direction and the wind is blowing due south, the wind will affect how and when the plane arrives.

Trigonometry applications will assist in determining the third side of the triangle, which will direct the plane in the correct direction; the plane will actually travel with the force of the wind added to its trajectory.

4. Archaeologists


To properly divide the excavation sites into equal labor zones, trigonometry is used. Archaeologists also utilize trigonometric ratios to assist them to identify the various tools employed by the culture and determining how far subterranean water pipes are.

5. Marine Biology

Can we use trigonometry under the water?……….

You will be amazed to know that trigonometry is not only used on the land or in the air but also under water. Trigonometry is frequently used by marine biologists to determine how light levels at various depths affect algae’s capacity to photosynthesize, the distance between celestial bodies, to analyze the behavior of sea organisms, and estimate the size of wild creatures from distance, etc.

6. Navigation


Trigonometry is used to set directions such as north, south, east, and west, and it informs you how to use the compass to get on a straight path.

It is used to locate a position in navigation and determine what lies beyond the horizon. It’s also used to figure out how far a point in the water is from the shore. 

7. Criminal Investigation

Criminal Investigation

Using Trigonometry applications in getting hold of criminals sounds exciting and fun. To deduce what happened at a crime scene, forensic scientists and crime detectives apply trigonometry formulae, examine blood splatter, analyze gunshot holes to determine the angle of impact, and use navigation technologies to pinpoint a criminal’s location.

8. Medical Science

Medical Science

Trigonometry applications in medical science in the orthopedics department aids in detecting the degree of vertebral distortion and whether nerves have been damaged. It’s also utilized to tailor the dimensions of prosthetic arms and legs so that they can function at their best.

Trigonometry is also used to diagnose and cure ailments using imaging, ultrasound, nuclear medicine, and magnetic resonance techniques. They also use it to determine accurate angles, which allows each beam to precisely target cancerous cells.

9. Music


Music and Trigonometry? 

Yes, Sine waves from trigonometry will assist you in creating your own sounds. Sine waves are a single note, but chords are made up of numerous sine waves. Understanding how these components interact allows music directors to achieve the desired sound.

10. Astronomy


Since the dawn of civilization, humans have been attracted by the solar system. Trigonometry is used by astronomers to determine how far away stars and planets are from Earth. When scientists develop and launch space shuttles and rockets, they utilize trigonometric identities to determine the distances between planets and stars.

Key Takeaways

In this blog, we have discovered various fields where Trigonometry is used. We also got to know how we can apply Trigonometry and reap benefits in our daily lives. We need to acknowledge that math is everywhere around us, we have to look deeper.
