Etymology

The term 'trigonometry' originates from the Greek words 'trigonon', meaning 'triangle', and 'metron', meaning 'measure'. The roots of trigonometry can be traced back to ancient civilizations, including the Greeks, who developed the concepts of calculating angles and sides of triangles. The earliest known trigonometric tables can be traced to ancient Babylonian and Indian mathematicians. The Greek mathematicians Hipparchus and Ptolemy made significant contributions to the field. Trigonometry became crucial in astronomy for measuring the distances to celestial bodies. The word itself was first used in the 16th century, reflecting a growing interest in mathematics during the Renaissance period. Today, trigonometry is fundamental not only in pure mathematics but also in fields such as physics, engineering, and computer science.
