algorithm
algorithm
[名詞]

a finite sequence of well-defined, mathematical instructions for completing a specific task or solving a problem

アルゴリズム

アルゴリズム

Ex: The Euclidean algorithm is used to find the greatest common divisor of two integers. 
variance
variance
[名詞]

a measure of the dispersion or spread of a set of data points in statistics, representing the average squared deviation from the mean

分散

分散

Ex: In statistics, variance is a measure of how spread out the values in a data set are around the mean. 
derivative
derivative
[名詞]

the rate at which a function changes with respect to its independent variable

導関数, 微分

導関数, 微分

Ex: Calculating the derivative of a position function yields the velocity function, describing the rate of change of position with respect to time. 
integral
integral
[名詞]

a mathematical concept representing the total accumulation of a quantity, often represented by the area under a curve on a graph

積分, 定積分

積分, 定積分

Ex: The definite integral of a velocity function over a time interval gives the total displacement of an object during that time. 
limit
limit
[名詞]

the value that a function or sequence approaches as its input or index gets close to a particular value

限界

限界

Ex: In calculus, the concept of a limit is essential for defining derivatives, as it involves understanding how a function behaves near a given point. 
catastrophe theory

a branch of mathematics that studies and classifies phenomena characterized by sudden shifts in behavior arising from small changes in circumstances

カタストロフ理論, 破局理論

カタストロフ理論, 破局理論

Ex: Catastrophe theory, introduced by French mathematician René Thom in the 1960s, is a branch of mathematics that studies sudden changes in the behavior of systems as a result of small changes in inputs or parameters. 
differential
differential
[名詞]

(mathematics) a really small change in a function or variable

微分, 無限小変化

微分, 無限小変化

Ex: The differential dx represents a small change in the variable x. 
logarithm
logarithm
[名詞]

a mathematical function that represents the exponent to which a fixed number, called the base, must be raised to produce a given number

対数

対数

Ex: In the logarithm log₂(8) = 3, the base 2 raised to the power of 3 equals 8. 
prime
prime
[名詞]

a natural number greater than 1 that has no positive divisors other than 1 and itself

素数, 素

素数, 素

Ex: Seven is a prime because it's only divisible by 1 and 7. 
vector
vector
[名詞]

an ordered set of numbers that describes both magnitude and direction, commonly used to represent quantities like displacement, velocity, or force in physics and engineering

ベクトル, ベクトル

ベクトル, ベクトル

Ex: In physics, force is often represented as a vector, considering both its magnitude and direction. 
theorem
theorem
[名詞]

a statement or proposition that has been proven to be true based on previously established axioms, definitions, and other theorems within a particular mathematical or logical system

定理

定理

Ex: Mathematicians often prove theorems to establish mathematical truths. 
permutation
permutation
[名詞]

(mathematics) a rearrangement of a set of elements in a specific order or sequence

順列, 配列

順列, 配列

Ex: The number of permutations of three distinct objects is six. 
eigenvalue

[名詞]

a special number used in linear algebra to describe how vectors change during transformations

固有値, 特性値

固有値, 特性値

Ex: Eigenvalues help us understand how matrices transform vectors. 
set theory
set theory
[名詞]

a branch of mathematics that deals with the study of sets, which are collections of distinct objects, and their properties, relationships, and operations

集合論, セット理論

集合論, セット理論

Ex: Set theory helps define relationships between different groups of numbers. 
polynomial
polynomial
[名詞]

a mathematical expression with variables raised to powers and combined using arithmetic operations
