A system of equations that has no solutions.
Increasing Function
A function whose value increases continuously as we move from left to right of its graph is called increasing function. A line with positive slope is a perfect example of increasing function where the value of the function increases as we proceed on the x-axis. If the increasing function is differentiable then its derivative at all points (where the function is increasing) will be negative.
Indefinite Integral
I = a∫bf(x) dx, is known as the improper integral
Indefinite Integral Rules
Independent Events
If the occurrence or non-occurrence of two events is independent of each other it is called as the independent event.
Independent Variable
The quantity in an equation whose values can be freely chosen in an equation without taking into consideration the values of the other variables.
Indeterminate Expressions
An undefined expression that cannot be assigned any value. There are various forms of indeterminate expressions:
i
In complex number analysis, the letter i denotes iota. Mathematically, iota is given by negative square root of 1, that means √-1. = i
Icosahedron
Icosahedron is a polyhedron with 20 faces. In the case of a regular icosahedron, the faces are all equilateral triangles.
Identity (Equation)
An equation that is true for any values of the variable. For example, the identity, sin2θ + cos2θ = 1 is true for all values of θ.
Identity Function
The function f(x) = x is called as the identity function.
Identity Matrix
A square matrix that has 1 as its element in the principal diagonal and rest all elements are zero.
Image of a Transformation
The image obtained after performing the operations of dilation or rotation or translation.
Imaginary Numbers
A complex number like 7i, that is free of the real part is called as the complex number.
Imaginary Part
Consider a complex number -7 + 8i, the coefficient of i called as the imaginary part of the complex number.
Implicit Function or Relation
A function in which the dependent variable can't be exactly expressed as a function of the independent variable.
Implicit Differentiation
Differentiating an implicit function. For example, consider 4x2 + 5y5 - 6x = 1. Here, y can't be written explicitly as a function of x.
Impossible Event
An event that is impossible to happen or an event whose probability is zero.
Improper Fraction
A fraction that has denominator greater than its numerator.
Improper Integral
A integration in which the bounds of integration has discontinuities in the graph. They can also have limits between ∞ and -∞. The discontinuities between the bounds of integration makes the use of limits necessary in evaluating improper integrals.
Improper Rational Expression
If the degree of a numerator polynomial is more than or equal to the degree of a denominator polynomial than the rational expression is called as the improper rational expression.
Incenter
The center of a circle inscribed in a triangle or a polygon. Geometrically, incenter is the point of intersection of the angle bisectors of a triangle.
Incircle
The largest possible circle that can be drawn inside a plane figure. All triangles and regular polygons have incircle.
Inconsistent System of Equations
A system of equations that has no solutions.
Increasing Function
A function whose value increases continuously as we move from left to right of its graph is called increasing function. A line with positive slope is a perfect example of increasing function where the value of the function increases as we proceed on the x-axis.

Indeterminate Expressions
An undefined expression that cannot be assigned any value. There are various forms of indeterminate expressions:
- 0/0
- ±∞/±∞
- 00
- 1∞
- ∞0
- ∞ - ∞
Induction
A method of proving a mathematical problem by the help of a series of steps. Mathematical induction is used to prove complex mathematical problems.
Independent Events
Two or more events are said to be independent events if the occurrence or non-occurrence of any of these events doesn't affect the occurrence or non-occurrence of others. By the principle of probability, if A and B are two independent events, then P(A|B) = P(A).
Independent Variable
Independent variables are those whose value can be chosen without any restriction. For example, in the equation Y = 2x2 + 3x, y is the dependent variable and x is the independent variable.
Indirect Proof
Proving a statement or a fact by the method of contradiction is known as indirect proof. This means that the conjecture is taken to be false and then it is proved that the statement contradicts the assumption made at the beginning of solving the problem.
