Mapping the Real-World Utility of Trigonometric Functions in the 21st Century

Abstract

Trigonometric functions, once developed for astronomical and geometric studies, have evolved into essential tools across modern scientific and technological domains. This research paper explores the real-world utility of trigonometric functions in the 21st century, emphasizing their application in engineering, navigation, architecture, digital technology, and environmental sciences. By integrating theoretical concepts with real-world examples, the study highlights how trigonometry contributes to problem-solving, system modeling, and innovation. The paper further demonstrates that trigonometric principles remain foundational in emerging technologies such as satellite communication, robotics, and computer graphics.
