People who contributed to trigonometry?
Some key contributors to the development of trigonometry include ancient civilizations such as the Babylonians and Egyptians, who used rudimentary trigonometric concepts for practical purposes. The Greek mathematician Hipparchus is often credited with formalizing the field of trigonometry, introducing the trigonometric functions and developing the earliest trigonometric tables. Later, Islamic mathematicians such as Al-Battani and Al-Khwarizmi made significant advancements in trigonometry, further expanding its applications in astronomy, geography, and mathematics. These early pioneers laid the foundation for the modern study and application of trigonometry in various fields.
What are the contribution of georg von purbach to trigonometry?
He made his observations with very simple instruments, using an ordinary plumb-line to measure the angles of elevation of the stars. He also introduced a mathematical innovation by using Hindu-Arabic numerals in his sine tables, the first transition from the duodecimal to the decimal system.
