Taylor's theorem, an Uncommon card

The card carries these facts from its Wikipedia article.

• For a smooth function, the Taylor polynomial is the truncation at the order k {\textstyle k} of the Taylor series of the function.
• The first-order Taylor polynomial is the linear approximation of the function, and the second-order Taylor polynomial is often referred to as the quadratic approximation.
• There are several versions of Taylor's theorem, some giving explicit estimates of the approximation error of the function by its Taylor polynomial.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Taylor's theorem article was read about 170,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 62: each hit it takes is cut by 25 %.

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.
