Parametric equation quiz: 3 questions
Three questions on the Parametric equation card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
In the case of two parameters, the point describes a ______, called a parametric surface.
Answer
surface. In the case of two parameters, the point describes a surface, called a parametric surface. From the Parametric equation article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Natural philosophy. Natural philosophy 72 · Photocopier 69 · Parametric equation 65 · Loka 62 ATK in WikiCards.
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.
- In the case of a single parameter, parametric equations are commonly used to express the trajectory of a moving point.
- For this case, the parameter is often, but not necessarily, time, and the point describes a curve, called a parametric curve.
- In the case of two parameters, the point describes a surface, called a parametric surface.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Parametric equation article was read about 60,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 56: each hit it takes is cut by 22 %.
How to get Parametric equation
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.
