Inverse hyperbolic functions, an Uncommon card
In mathematics, the inverse hyperbolic functions are inverses of the hyperbolic functions, analogous to the inverse circular functions.

Inverse hyperbolic functions quiz: 3 questions
Three questions on the Inverse hyperbolic functions card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
They are commonly denoted by the symbols for the hyperbolic functions, prefixed with arc- or ar- or with a ______ − 1.
Answer
superscript. They are commonly denoted by the symbols for the hyperbolic functions, prefixed with arc- or ar- or with a superscript − 1. From the Inverse hyperbolic functions article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Knot. Knot 71 · Inverse hyperbolic functions 68 · Bijection, injection and surjection 61 · Bichon 54 ATK in WikiCards.
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.
- There are six in common use: inverse hyperbolic sine, inverse hyperbolic cosine, inverse hyperbolic tangent, inverse hyperbolic cosecant, inverse hyperbolic secant, and inverse hyperbolic cotangent.
- They are commonly denoted by the symbols for the hyperbolic functions, prefixed with arc- or ar- or with a superscript − 1.
- For a given value of a hyperbolic function, the inverse hyperbolic function provides the corresponding hyperbolic angle measure, for example arsinh = a and sinh = x. Hyperbolic angle measure is the length of an arc of a unit hyperbola x 2 − y 2 = 1 as measured in the Lorentzian plane, and twice the area of the corresponding hyperbolic sector.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Inverse hyperbolic functions article was read about 62,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 54: each hit it takes is cut by 22 %.
How to get Inverse 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.
