Math Terms StartingWith I





In this page math terms startingwith i we are going to see definitions of mathematical terms starting with the letter "I". We have listed out almost terms in math starting with I.In math also it is very important to know the meaning of many important words which are being used in the subject math.Each term is defined and examples are provided where ever it is necessary. Links are given for every words, by using this students can learn the meaning and its application more clearly.Here are the math terms startingwith i.

Terms

Definition

Icosahedron

A polygon with 20 faces.

Identity

An equality that holds regardless of the values of its variables.

Improper fraction

A fraction in which the numerator is greater or equal to its denominator.

Inch

An inch is the name of unit of length in a number of different systems like imperial units and united states customary units.

In center

The center of the circle that is inscribed in a triangle.

Isosceles Triangle

A triangle with two equal sides is called isosceles triangle. The angles which are opposite to equal sides are equal.In the following triangle the sides AB and AC are equal and angles B and C are also equal.

Integers

Integers are set of all whole numbers and their opposites. We are using number line to denote integers....-3, -2, -1, 0, 1, 2, 3....

Interior angles

In the following diagram the angles 1 and 3 and 2 and 4 represents interior angles.

Inverse Variation

we can say two quantities are said to be in inverse variation if one quantity increases,then the other quantity decreases or when one quantity decreases,the other quantity increases.

Identity function

A function f from a set A to the same set A is said to be identity function if f(x) = x for all x ∈ A. If A-> A is defined by f(x) = x for all x ∈ A. Example of identity function is y = x.

Inverse function

To define the inverse of a function f the function must be one-to-one and onto.

Implicit function

When the relation between x and y is given by an equation in the form of f(x,y) = 0 and the equation is not easily solvable for y, then y is said to be implicit function.

Infinite set

A set which contains uncountable elements is called as an infinite set. In other words, a set whose cardinal number is uncountable is called as an infinite set.

For example

  • A= set of all whole numbers.           The cardinal number of A is not countable, so A is infinite.
Integration

A function g(x) is called am anti derivative or integral of a function g(x) on an interval I. If g'(x) = g(x) for every value of x in I.

Image

The element of B associated with x is called image of x under f.

Interval

A subset of the real line is called interval if it contains atleast two numbers it contains all numbers between the two elements.

Example of intervals

The set of all real numbers between -2 < x < 2.

Inequality

Mathematical equation that contains greater than or less than (< or >) and not equal (≠) symbols. a < b, x+y>2z.

Independent variable

A variable is said to be an independent variable if it has any arbitrary values.

These are the word in math terms startingwith i.
