C
Complex Number
A complex number is a type of number that includes a real part and an imaginary part. It is expressed in the form a + bi, where 'a' is the real part and 'bi' is the imaginary part, with 'i' representing the square root of -1.
BeginnerMathematics2 min
C
Composite Number
A composite number is a positive integer that has more than two distinct positive divisors. This means it can be divided evenly by numbers other than one and itself.
BeginnerMathematics2 min
D
Derivative
A derivative is a concept in mathematics that measures how a function changes as its input changes. It essentially tells us the rate of change or the slope of the function at any given point.
BeginnerMathematics2 min
D
Determinant
A determinant is a special number that can be calculated from a square matrix. It provides important information about the matrix, such as whether it has an inverse and the volume scaling factor for transformations represented by the matrix.
BeginnerMathematics2 min
D
Differential Equation
A differential equation is a mathematical equation that relates a function to its derivatives. It describes how a quantity changes over time or space, making it essential in modeling various real-world phenomena.
BeginnerMathematics2 min
D
Domain / Range
The domain of a function is the set of all possible input values, while the range is the set of all possible output values. Together, they define the limits of what a function can take and produce.

E
Eigenvalue
An eigenvalue is a special number associated with a square matrix that indicates how much a corresponding eigenvector is stretched or compressed during a linear transformation. It is a key concept in linear algebra, used in various applications such as systems of differential equations and stability analysis.
BeginnerMathematics2 min
E
Equation
An equation is a mathematical statement that shows the equality between two expressions. It often contains variables and constants, and it can be solved to find the value of the variables.
BeginnerMathematics2 min
E
Euclidean Geometry
A branch of mathematics, this type of geometry deals with flat surfaces and the relationships between points, lines, and angles. It is based on the work of the ancient Greek mathematician Euclid and is fundamental to many areas of math and science.
BeginnerMathematics2 min
E
Exponent
An exponent is a mathematical notation that indicates how many times a number, known as the base, is multiplied by itself. For example, in the expression 2^3, 2 is the base and 3 is the exponent, meaning 2 is multiplied by itself three times, resulting in 8.
BeginnerMathematics2 min
F
Factoring
Factoring is the process of breaking down a number or an expression into its component parts, called factors, which when multiplied together give the original number or expression. It is an essential concept in mathematics that helps simplify problems and solve equations.
BeginnerMathematics2 min
F
Fundamental Theorem of Calculus
The Fundamental Theorem of Calculus links the concept of differentiation with that of integration. It shows that these two operations are essentially inverse processes, allowing us to compute the area under a curve using antiderivatives.

I
Inequality
Inequality refers to a mathematical statement that compares two expressions and shows that one is not equal to the other. It can indicate relationships such as greater than, less than, or not equal, and is fundamental in various fields of mathematics.
BeginnerMathematics2 min
I
Integer
An integer is a whole number that can be positive, negative, or zero. It does not include fractions or decimals, making it a fundamental concept in mathematics.
BeginnerMathematics2 min
I
Integral
An integral is a fundamental concept in mathematics that represents the area under a curve. It helps in calculating quantities like distance, area, and volume when given a function.
BeginnerMathematics2 min
I
Irrational Number
An irrational number is a type of real number that cannot be expressed as a simple fraction. This means that its decimal representation goes on forever without repeating. Examples include numbers like pi and the square root of 2.
