In differential calculus and differential geometry, an inflection point, point of inflection, flex, or inflection is a point on a smooth plane curve at which the curvature changes sign.

Inflection point quiz: 3 questions
Three questions on the Inflection point card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
A point where the second derivative vanishes but does not change its sign is sometimes called a point of ______ or undulation point.
Answer
undulation. A point where the second derivative vanishes but does not change its sign is sometimes called a point of undulation or undulation point. From the Inflection point article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Black–Scholes equation. Black–Scholes equation 61 · Inflection point 55 · Kappa2 Apodis 52 · DUSP12 45 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Inflection point. Inflection point 69,000 · Deflagration 47,000 · Kappa2 Apodis 300 · DUSP12 230 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.
- In particular, in the case of the graph of a function, it is a point where the function changes from being concave to convex, or vice versa.
- For the graph of a function f of differentiability class C2, the condition f'' = 0 can also be used to find an inflection point since a point of f'' = 0 must be passed to change f'' from a positive value to a negative value or vice versa as f'' is continuous, an inflection point of the curve is where f'' = 0 and changes its sign at the point.
- A point where the second derivative vanishes but does not change its sign is sometimes called a point of undulation or undulation point.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Inflection point article was read about 69,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 55 and blocks with 31: each hit it takes is cut by 12 %.
How to get Inflection point
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.
