Trigonometry is more than just solving triangles in math class — it’s a powerful tool with real-world applications across science, technology, engineering, and even entertainment. Whether you’re calculating heights, navigating distances, or designing virtual worlds, trigonometry is everywhere.
In this blog post, we’ll explore 7 real-life applications of trigonometry that demonstrate its importance and usefulness in everyday life and various careers.
What is Trigonometry?
Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. It involves trigonometric ratios like sine (sin), cosine (cos), and tangent (tan). These ratios are key to solving problems involving height, distance, direction, and wave motion.
Top 7 Applications of Trigonometry
