Lebesgue integral, an Uncommon card
In mathematics, the integral of a non-negative function of a single variable can be regarded, in the simplest case, as the area between the graph of that function and the x-axis.

The facts on the card
The card carries these facts from its Wikipedia article.
- The Lebesgue integral, named after French mathematician Henri Lebesgue, is one way to make this concept rigorous and to extend it to more general functions.
- The Lebesgue integral is more general than the Riemann integral, which it largely replaced in mathematical analysis since the first half of the 20th century.
- It can accommodate functions with discontinuities arising in many applications that are pathological from the perspective of the Riemann integral.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Lebesgue integral article was read about 100,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 74 and blocks with 54: each hit it takes is cut by 22 %.
How to get Lebesgue integral
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.
