Study Notes
Emergence of Trigonometry
- The field of trigonometry emerged in the 3rd century BC.
Focus of Trigonometry
- Trigonometry delves into the relationships between angles and sides of triangles.
Applications of Trigonometric Identities
- Trigonometric identities are commonly employed in simplifying complex expressions involving trigonometric functions.
- They are broadly used in solving trigonometric equations and proving other trigonometric identities.
Early Development of Trigonometry
-
The earliest known tables of values for trigonometric ratios were crafted by the ancient Greek mathematician Hipparchus in the 2nd century BC.
-
Ancient Nubians utilized a method involving the rising and setting of stars to determine the time of year. They essentially applied rudimentary principles related to trigonometry.
-
Sumerian astronomers used a sexagesimal system (base 60) for measuring angles, which paved the way for today's system of degrees, minutes, and seconds for angle measurements.
-
The ancient Egyptians and Babylonians explored the ratios of the sides of similar triangles, a concept that forms the foundation of trigonometry.
