Hipparchus, a Greek astronomer, geographer, and mathematician, is widely considered the father of trigonometry.
Hipparchus's Contributions
Hipparchus, who lived in the 2nd century BC, made significant advancements in the field, laying the groundwork for future developments. While he didn't invent trigonometry as we know it today, he is credited with:
- Creating the first trigonometric table: This table allowed for the systematic calculation of angles and their corresponding sides in triangles. This was a crucial step in developing the field.
- Systematically studying and developing trigonometric concepts: He applied trigonometric principles to astronomy, using them to solve problems related to celestial positions and movements.

While other mathematicians built upon his work, Hipparchus's contributions are foundational to the field of trigonometry. His pioneering work in creating the first trigonometric tables and applying trigonometry to astronomical problems firmly establishes him as the father of trigonometry.
