Power 148 (ATK + DEF): stronger than 75 % of WikiCards cards.
Derivative quiz: 3 questions
Three questions on the Derivative card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The tangent line is the best linear approximation of the ______ near that input value.
Answer
function. The tangent line is the best linear approximation of the function near that input value. From the Derivative article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
French Revolutionary Wars. French Revolutionary Wars 83 · Derivative 78 · Inclined plane 73 · Wilhelm Röntgen 70 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Derivative. Derivative 310,000 · Inclined plane 44,000 · Neural crest 30,000 · Antlia 20,000 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.
- The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point.
- The tangent line is the best linear approximation of the function near that input value.
- The derivative is often described as the instantaneous rate of change, the ratio of the instantaneous change in the dependent variable to that of the independent variable.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Derivative article was read about 310,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 78 and blocks with 70: each hit it takes is cut by 28 %.
How to get Derivative
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.
