10 Reasons Why Should One Study Trigonometry? What Are The Applications Of It?

Many students avoid trigonometry as it can be a complicated concept, but that can be addressed by learning the tips and tricks for maths taught by the teachers of TISA. Despite this, students wonder why they need to learn trigonometry.

They don't understand its application as people usually study the concept but fail to relate it to real life. However, trigonometry is actually used in many real-world situations and professions.

So, here are 10 reasons why one should study trigonometry.

Important Role in Engineering

Engineers from various fields collaborate on projects such as gear design, infrastructure, antenna design, sound wave analysis, and marine vessel design, with trigonometric formulas and diagrams in the background

Be it mechanical, civil, electrical, sound, or even the marine branch, trigonometry in engineering plays an important role in helping you understand how things work and what approach would be best for solving problems in that area.

In mechanical engineering, trigonometry helps you to understand the movements of various mechanisms and design things like gears, pulleys, and more.

Civil engineers use the knowledge of trigonometry for sound construction of various infrastructure projects. 

Electrical engineers also make use of trigonometry in areas like antenna designing, signal processing, and more. Sound engineers need trigonometry for analyzing sound waves and designing audio systems.

Marine engineering is a field that involves the designing of marine vessels, which is something that requires an extensive use of trigonometry.

If you wish to keep any of these as a career option, trigonometry needs to be your best friend.

Useful in Understanding Architecture

If you are passionate about architecture, you will find trigonometry to be an invaluable tool for understanding this field. Architects rely on their knowledge of trigonometry to design structures with accurate roof slopes, surface areas, and other important features.

In addition, understanding structural loads requires a good grasp of trigonometry. Even basic tasks like creating shade or maximizing sunlight in certain areas of a building require the use of trigonometry.

Trigonometry in architecture can unlock a world of possibilities in the field of architecture.

Helps to Dive Deep Into Physics and Astronomy

Learning how to calculate where light will fall and at which angle, the basics of projectile motion, oscillation, and more is possible with the help of trigonometry. Studying the movement of celestial bodies, gravitational forces, and more is also done using trigonometry in Astronomy.

Meteorology also involves its use in determining weather patterns, lunar phases, the time of sunrise and sunset, etc. Trigonometry is a fascinating subject that can help you understand the underlying mathematical principles of physics and astronomy.

Critical for Learning Navigation

Navigation is not as simple as it looks. Things that make navigation easy, like maps and GPS, are only made possible with the use of trigonometry.

It helps in calculating distances and angles, as well as the location of various objects in relation to a particular reference point. So, if you thought that there would be no use of trigonometry in Geography, now you know exactly how it is involved.

This disproves the notion that this is a subject that is limited to the realm of mathematics.

Useful in the World of Computer Graphics and Animation

Video games where characters jump off buildings, cross obstacles, fire projectiles and more are possible because a lot of mathematics goes into it.

Trigonometry in computer graphics and animation is responsible for producing the stunning visual effects that we see on screen in the form of video games and other similar animations.

Professionals in the field of graphic design and animation utilize various trigonometric techniques and concepts to achieve high-quality output, making it a crucial part of their work.

Role of Trigonometry in Art and Design

Art may be a creative field but you still need mathematics to get certain things right. Bringing reality to paper, or in the case of designing, to the screen requires knowledge of trigonometry because it familiarises you with angles, perspective, and more.

Whether it is a painting, sketch, or design, there is a need for balance and harmony that can only be achieved through trigonometry. Even the placement of light and dark in any art piece requires some knowledge of this subject.

Improves Photography Skills

The use of trigonometry in photography comes when photographers need to calculate the best angle for light, camera position, and other aspects of composition to capture the desired image in that frame.

Even a simple photograph requires a significant amount of calculations to make it perfect. Trigonometry helps to add a professional touch to it, making it more visually appealing. It can also be used for stereo photography to create a 3D effect in the image. 

Involvement of Trigonometry in Healthcare

Although it may not be obvious, the healthcare industry relies heavily on mathematical concepts to carry out many fundamental tasks. For instance, medical professionals use the principles of trigonometry to determine the location and dimensions of organs in relation to one another.

These calculations allow doctors to gain a better understanding of the physical characteristics of organs, which is not only important for diagnosis and treatment but for overall patient care as well. Doctors also use trigonometry to read MRI and CT scans.

Use of Trigonometry in Finance

Trigonometry plays a crucial role in financial mathematics, even though it is a branch of mathematics that deals with the relationships between the sides and angles of triangles. By using trigonometry, financial experts can analyze financial charts, predict market trends, and manage investment portfolios.

If you get proper career guidance, you will learn much more about this field. It may come as a surprise, but this area of mathematics is a powerful tool that helps individuals and businesses make informed financial decisions.

Teaches How to Measure Height and Distance

Having the ability to measure height and distance accurately is a vital skill in various professions. Trigonometry in construction plays a significant role, enabling professionals to measure height and distance with precision.

Learning how to measure height and distance can be a valuable skill that can enhance your professional capabilities and also help you in your day-to-day life.

The Bottom Line

These are a few fields where trigonometry can be used along with reasons why it should be studied. Consulting TISA maths teachers on this matter can grant further clarity to students who are curious about Trigonometry and its applications.

If students study it diligently, it can be an extremely interesting subject, especially due to its connection to one's daily life. With its use in numerous professional fields, it can also present many career options that can bring incredible success.


TISA math labs are equipped with many tools that can not only develop your interest in trigonometry but also explain its concepts thoroughly. So, it is a great starting point for those looking to dive deep into the world of trigonometry.
