Gamma function, an Epic card
In mathematics, the gamma function, denoted by Γ , is the most common extension of the factorial function to complex numbers.

Power 165 (ATK + DEF): stronger than 85 % of WikiCards cards.
Gamma function quiz: 3 questions
Three questions on the Gamma function card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Since the gamma function has no zeros, its ______ 1 / Γ is an entire function.
Answer
reciprocal. Since the gamma function has no zeros, its reciprocal 1 / Γ is an entire function. From the Gamma function article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Nuclear fusion. Nuclear fusion 88 · Gamma function 84 · Mr. Olympia 80 · Antibiotic sensitivity testing 73 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Gamma function. Gamma function 530,000 · Ceramic capacitor 41,000 · Pollution in China 29,000 · Antibiotic sensitivity testing 15,000 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.
- First studied by Daniel Bernoulli, the gamma function is defined for all complex numbers z except non-positive integers, and satisfies Γ = ! for every positive integer n .
- The gamma function can be defined via a convergent improper integral for complex numbers with positive real part: Γ = ∫ 0 ∞ t z − 1 e − t d t, ℜ > 0. The gamma function then is defined in the complex plane as the analytic continuation of this integral function: it is a meromorphic function which is holomorphic except at zero and the negative integers, where it has simple poles.
- Since the gamma function has no zeros, its reciprocal 1 / Γ is an entire function.
Why it is Epic
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Gamma function article was read about 530,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 84 and blocks with 81: each hit it takes is cut by 32 %.
How to get Gamma function
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.
