| Cartesian
Coordinate Plane |
A
rectangular coordinate system containing an x and y-axis and
four quadrants. Each point in the coordinate plane can be
specified by an ordered pair of numbers. The coordinate system
was created by Rene Descartes. |
| Census |
A
survey in which each item in a population is examined. |
| Clustered
Sample |
A
sample taken from a particular segment of the population. |
| Coefficient |
A
number that is located in front of a variable in a monomial
expression. For example, in the expression 2x + 5y, the coefficients
are 2 and 5. |
| Combination |
The
arrangement of a set of objects without regard to the order
in which the objects are selected. |
| Common
Factor |
A
factor of two or more numbers or expressions. |
| Conjugate |
Numbers
such as 3 + 2i and 3 - 2i are conjugates. They differ only in
the sign between the terms. |
| Constant |
A
monomial expression which is a number. It contains no variable
and is generally located at the end of an expression. |
| Consistent-Dependent |
A
classification for a system of linear equations indicating the
system has coinciding lines and therefore infinite solutions. |
| Consistent-Independent |
A
classification for a system of linear equations indicating the
system has intersecting lines and therefore one solution. |
| Convenience
Sample |
A
non-random sample chosen by taking a sample that is easiest
to take. |
| Coordinates |
A
ordered pair of numbers (x, y) that identifies a point on the
Cartesian coordinate plane. The first number in the ordered
pair identifies the position with regard to the x-axis while
the second number identifies the position on the y-axis. |
| Cosecant
(Csc) |
For
any acute angle in a right triangle, the ratio of the length
of the hypotenuse, to the length of the side opposite. Csc x
= 1/sin x |
| Cosine
(Cos) |
For any acute angle in a right triangle, the ratio of the length
of the adjacent side, to the length of the hypotenuse.
|
| Cotangent
(Cot) |
For
any acute angle in a right triangle, the ratio of the length
of the opposite side, to the length of the adjacent side. Cot
x = 1/tan x |
| Coterminal
Angles |
Two
angles, drawn in standard position, whose terminal arms coincide.
