What is Trigonometry?

Trigonometry is a branch of mathematics that studies the relationship between the ratios of a right-angled triangle's sides and its angles. Trigonometric ratios, such as sine, cosine, tangent, cotangent, secant, and cosecant, are used to study these relationships.

Trigonometry is the most important concept in Mathematics. It plays an important role in almost all the fields, whether it's Aviation, Physics, Criminology, Military, etc. Trigonometry is used for finding the angles or the sides of the triangle.


Basics of Trigonometry 

The measurement of angles and problems involving angles are covered in the basics of trigonometry. Trigonometry has three basic functions: sine, cosine, and tangent. Other essential trigonometric functions can be derived using these three basic ratios. These functions form the foundation for all of the fundamental topics in trigonometry. In conclusion, the six main functions of an angle that are commonly used in trigonometry are as follows:

  • sine (sin), 

  • cosine (cos), 

  • tangent (tan), 

  • cotangent (cot), 

  • secant (sec), and 

  • cosecant (csc).


Applications of Trigonometry

Trigonometry has been used in a variety of fields throughout history, including architecture, theoretical physics, and surveying. It can be used for a variety of things, including:

  • Oceanography, seismology, meteorology, physical sciences, astronomy, acoustics, navigation, electronics, and many other subjects are among them.

  • It may also be used to determine the length of lengthy rivers, measure the height of a mountain, and so on.

  • Solar, lunar, and stellar locations have all been calculated using spherical trigonometry.


Real-Life Applications of Trigonometry

Many real-life examples are used frequently in trigonometry. Let's use an example to better understand trigonometry. A young boy stands beside a tree. "How tall is the tree?" he wonders as he looks up at it. The tree's height can be determined without having to measure it. A right-angled triangle, or one with one of the angles equal to 90 degrees, is what we have here. If the distance between the tree and the boy, as well as the angle produced when the tree is viewed from the ground, trigonometric formulas can be used to compute the tree's height.


Other Applications include:

  • Trigonometry can be used to measure the height of a building or mountains

  • Trigonometry is used video games

  • Trigonometry is used in construction

  • Trigonometry is used in flight engineering

  • Trigonometry is used in physics

  • Archeologists use trigonometry

  • Trigonometry is used in criminology

  • Trigonometry is used in marine engineering

  • Trigonometry is used used in navigation


Conclusion

Trigonometry is the branch of mathematics that studies the relationship between angles and sides of a triangle. It is possible to calculate the heights of large mountains or structures using trigonometry; it is also used in astronomy to calculate the distance between stars or planets, and it is frequently used in physics, architecture, and GPS navigation systems. 

FAQs on Trigonometric Applications

1. How is Trigonometry used in construction sites?

Trigonometry is used on building sites to compute the following:

  • Measuring the size of plots and fields on the ground

  • Taking measurements of the ground's surface

  • Constructing a building that is perpendicular and parallel

  • Roof slopes and roof inclination

  • Ceramic tiles and stones are being installed.

  • The building's height and width.

  • Sun shading and light angles

2. How is Trigonometry found useful and effective in real life?

Many real-life situations are evolving around trigonometric functions, such as measuring sea levels every time the tide changes, and measuring the length of each day as seasons change. Trigonometry is also mainly used to set directions such as the north-south or east-west, it will help you decide in what direction you should fix a compass to go in a straight direction. It is used in the navigation of routes in airlines and marine fields to pinpoint a location. It is also used to find the appropriate distance of the shore from a point in the sea.

3. Do Marine biologists study marine life using trigonometry?

Yes, Marine biologists study marine life in the ocean, including plants, animals, and other species. In marine biology, trigonometry is used to calculate how far and at what angle an organism or plant is from the scientist. Depending on where the viewer is, the angle could be a depression angle or an elevation angle. The item's depth is considered the height slant distance, while the water level is considered the base of the right-angled triangle.
