Trigonometry is a broad discipline whose foundation was laid by the Greek mathematician Hipparchus. Trigonometry is the study of the relationship between the sides and angles of a right-angled triangle, and it deals with the measurement of angles. In most cases, trigonometry begins with right-angled triangles.
What is Trigonometry Ratios?
Trigonometric ratios are the values of all trigonometric functions that are dependent on the value of the side ratio in a right-angled triangle. The angle’s trigonometric ratios are the trigonometric ratios of a right-angled triangle’s sides in relation to any of its sharp angles.
The hypotenuse (longest side), perpendicular (opposite side to the angle), and base are the three sides of a right triangle (Adjacent side to the angle).
Trigonometric functions or trigonometric ratios are used to express the connection between the angles and sides of a right-angled triangle with respect to any of its acute angles.
The following are the six trigonometric ratios:
- Sin θ =Perpendicular / Hypotenuse
- Cos θ= Base/ Hypotenuse
- Tan θ = Perpendicular / Base
- Cot θ= Base / Perpendicular
- Sec θ = Hypotenuse / Base
- Cosec θ = Hypotenuse /
Trigonometry Ratios’ Importance
Trigonometric ratios are important because they are used in a variety of places and subjects, including civil engineering, architecture, mechanical engineering, medical imaging, electronics, electrical engineering, astronomy, chemistry, geography, computer music development, oceanography, seismology, phonetics, image compression, game development, and so on.
Real-World Applications of Trigonometry Ratios
The Height of a Building or Mountain Can Be Measured Using Trigonometry
You can easily find the height of a structure if you know the distance from where you observe it and the angle of elevation. Similarly, you may discover another side in the triangle if you have the value of one side and the angle of depression from the top of the building. All you need is one side and the angle of the triangle.
Use of Trigonometry in Construction
We need trigonometry to measure the following in construction:
- Taking measurements of fields, lots, and places
- Creating parallel and perpendicular walls
- Ceramic tile installation
- The angle of the roof
- The height of a building, its width and length, and a variety of other situations where trigonometry is required
Use of Trigonometry in Flight Engineering
Flight engineers must take into account their own speed, distance, and direction, as well as the speed and direction of the wind. The wind plays a significant role in how and when a plane reaches its destination. This is addressed by constructing a triangle out of vectors, which is then solved using trigonometry.

Use of Trigonometry in Physics
In physics, trigonometry is used to find the components of vectors, model the mechanics of waves and oscillations (both physical and electromagnetic), add field strengths, and apply dot and cross products. Trigonometry is also widely used in projectile motion.
Archaeologists’ Use of Trigonometry
Trigonometry is utilised to appropriately divide the excavation sites into equal work zones. Archaeologists can utilise trigonometry to assist them to identify the various tools employed by the culture. They can also use it to determine how far subterranean water pipes are.
Trigonometry in Criminology
In criminology, trigonometry can be used to calculate the trajectory of a projectile, predict what would have caused a collision in a car accident, determine how an object fell down from somewhere, or determine the angle at which a bullet was fired, and so In criminology, trigonometry can be used to calculate the trajectory of a projectile, to predict what would have caused a collision in a car accident, to determine how an object fell down from somewhere, or to determine the angle at which a bullet was fired.
Trigonometry in Marine Biology
Trigonometry is frequently used by marine biologists to establish measurements. For example, to determine how light levels at various depths affect algae’s capacity to photosynthesize. The distance between celestial bodies is calculated using trigonometry. Marine biologists also use mathematical models to measure and analyse the behaviour of sea organisms. Trigonometry can be used by marine biologists to estimate the size of wild creatures from afar.
Trigonometry in Marine Engineering
Trigonometry is used in maritime engineering to build and navigate ships. Trigonometry is used to build the Marine ramp, which is a sloping surface that connects lower and higher-level locations; depending on its application, it can be a slope or even a staircase.
In Navigation, Trigonometry Is Used
Trigonometry is used to set directions such as north, south, east, and west, and it tells you the compass direction to take to get on a straight path. It is used in navigation to find a certain spot. It’s also used to calculate the distance between the shore and a location in the water. It’s also utilised for spotting the horizon.
Conclusion
Although trigonometry does not have direct applications in solving real problems, it is applied in a variety of activities that we like. For example, sound travels in waves in music, and this pattern, while not as regular as a sine or cosine function, is nonetheless important in computer music development. Because a computer cannot listen to or perceive music as we do, it is mathematically represented by its constituent sound waves. As a result, sound engineers must have a rudimentary understanding of trigonometry. And, thanks to trigonometry, the good music that these sound engineers create is used to help us relax from our bustling, stressful lives.
