The history of trigonometry goes back to the earliest recorded mathematics in Egypt.

• A. German
• B. Indian
• C. Babylon
• D. Japanese

The history of trigonometry indeed has ancient roots, with significant contributions from various civilizations. Among the options provided, the correct answer is:

Babylon

The Babylonians, around 2000 BCE, were among the first to develop early forms of trigonometric concepts, particularly in their astronomical calculations. They used a base-60 number system, which influenced later mathematical developments.

Key Contributions

• Astronomy: Babylonian astronomers utilized trigonometric principles to predict celestial events.
• Tables: They created tables of chords, which are early forms of trigonometric functions.

While other cultures, such as the Greeks and Indians, also made significant advancements in trigonometry, the earliest recorded use can be traced back to Babylonian mathematics.
