A true statement
that shows two mathematical expressions are equal for all values
where both expressions are defined. For example:
for all values of a and b.
A quotient of
two quantities in which the numerator has a greater absolute value
than the denominator, such as 9/5 or where
the numerator .is a polynomial of higher degree than the polynomial
in the denominator.
The angle forming
between a straight line (or its extension) and the positive direction
of the x-axis, measured positive in the counter clockwise direction
from the x-axis and negative in the clockwise direction from the
is not zero when a division is performed.
stating that one expression is than
Non linear inequalities
just two symbols, they are not real numbers.
Any of the positive
and negative whole numbers
coordinates plane, it is the (directional) distance from the origin
to the point at which the graph crosses either the x- or y-axis.
For example, the x-intercept of the line x/2+y/3=1
is 2 and the y-intercept is 3.
1. A point or
a set of points
that are common to two or more geometic figures.
2. The set of elements that are common to two or more given sets
See sets for examples.
Given a one-to-one
function f , its inverse function g exists and satisfies
g(f(x))=x for all x in the domain
of f and f(g(x))=x for all x
in the domain of g. In short we can say that g undo
what f does and vice verse.
A real number
that is not rational, i.e., can not be expressed as a quotient of
two integers with non-zero denominator. For example,
that can not be factored as the product of two polynomials with
degrees greater than or equal to one.
a selected variable or letter to one side of a given equation.
A triangle having
two sides of equal length. The angles opposite these two equal length
