The facts on the card
The card carries these facts from its Wikipedia article.
- Systematic study of trigonometric functions began in Hellenistic mathematics, reaching India as part of Hellenistic astronomy.
- In Indian astronomy, the study of trigonometric functions flourished in the Gupta period, especially due to Aryabhata, who discovered the sine function, cosine function, and versine function.
- During the Middle Ages, the study of trigonometry continued in Islamic mathematics, building on earlier foundations from Indian and Greek sources.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The History of trigonometry article was read about 49,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 82 and blocks with 91: each hit it takes is cut by 36 %.
