Study Notes
Trigonometry Overview
- The main focus of trigonometry is the relationships between the sides and angles of triangles.
History of Trigonometry
- Hipparchus, a Greek mathematician, created the earliest-known tables of values for trigonometric ratios.
- The field of trigonometry emerged in the 2nd century BCE.
Early Contributions
- Sumerian astronomers used the sexagesimal (base-60) number system for angle measure, which is why we have 60 seconds in a minute and 60 minutes in an hour.
Applications of Trigonometry
- Trigonometric identities are commonly used for simplifying complex calculations and solving triangular problems in various fields like physics, engineering, and navigation.
