RIC-1069 Maths terms and tables

List of mathematical terms
Independent events
Where the result of any one event does
not depend on the result of any other
previous event. [See also Dependent
events.]
e.g.
When tossing a coin, each toss is
independent as the result does
not depend on the outcome of
any other tosses.

[See Exponent]
Inequality
A number sentence showing a
relationship other than equality.
Infinite (Infinity, ∞)
Never ending.
e.g.
7 > 3, 3 < 7, 3 ≠ 7 are inequalities.
e.g.
Counting 1, 2, 3, 4, … can go
on without end; i.e. there is an
infinite set of counting numbers.
Inscribed
When a shape is made to fit inside a
second shape, the first shape is said to
be inscribed in the second.
e.g.
The circle is inscribed
in the triangle.
Intercept
The point at which a path crosses the
horizontal x-axis or the vertical y-axis
on a coordinate system; e.g. in the
diagram shown, the intercepts of line
segment AB are at x = 2 and at y = 1.
e.g.
A
1
y
0 1 2
B
x
Integers
The set of counting numbers, their opposites, and zero; i.e. … – 2, – 1, 0, 1, 2, …
[see p. 71].
Interior angles
The angles inside a shape; e.g. the
angles inside this polygon.
e.g.
Intersection
The point at which two or more paths
cross; e.g. X is the point of intersection
of the two line segments shown [like the
intersection of two streets].
e.g.
X
