Analytic function, an Uncommon card

The card carries these facts from its Wikipedia article.

• More precisely, a real or complex function is analytic at a point if, in some neighborhood of that point, it is equal to a power series centered there.
• The analytic function is therefore locally determined by coefficients of the series, or equivalently by derivatives of the function evaluated at the center of the series expansion.
• In other words, an analytic function is a function that is locally represented by a convergent Taylor series.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Analytic function article was read about 87,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 46: each hit it takes is cut by 18 %.

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.
