Sine and cosine quiz: 3 questions
Three questions on the Sine and cosine card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
For an angle θ, the sine and cosine ______ are denoted as sin and cos .
Answer
functions. For an angle θ, the sine and cosine functions are denoted as sin and cos . From the Sine and cosine article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Agoraphobia. Agoraphobia 940,000 · Sine and cosine 350,000 · UNESCO Global Geoparks 12,000 · Frederick W. Lanchester 8,000 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 sine and cosine of an acute angle are defined in the context of a right triangle: the sine of an acute angle of a right triangle is the ratio of the length of the side opposite that angle to the length of the longest side of the triangle, the hypotenuse, the cosine is the ratio of the length of the adjacent side to that of the hypotenuse.
- For an angle θ, the sine and cosine functions are denoted as sin and cos .
- The definitions of sine and cosine have been extended to any real value in terms of the lengths of certain line segments in a unit circle.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Sine and cosine article was read about 350,000 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 76: each hit it takes is cut by 30 %.
How to get Sine and cosine
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.
