Hyperbolic functions quiz: 3 questions
Three questions on the Hyperbolic functions card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Hyperbolic functions are used to express the angle of ______ in hyperbolic geometry.
Answer
parallelism. Hyperbolic functions are used to express the angle of parallelism in hyperbolic geometry. From the Hyperbolic functions article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Barbiturate. Barbiturate 630,000 · Hyperbolic functions 390,000 · Special routes of U.S. Route 62 790 · Binna Burra Cultural Landscape 590 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- Just as the points form a circle with a unit radius, the points form the right half of the unit hyperbola.
- Also, similarly to how the derivatives of sin and cos are cos and –sin, the derivatives of sinh and cosh are cosh and sinh.
- Hyperbolic functions are used to express the angle of parallelism in hyperbolic geometry.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hyperbolic functions article was read about 390,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 68: each hit it takes is cut by 27 %.
How to get Hyperbolic functions
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
