Circular functions
Trigonometric functions when applied to real numbers are circular functions

Completing the square
A method of adding a constant to an expression in order to form a perfect square

Constant
A letter or symbol that stands for a specific number,

Continuous function
A function that is continuous on its entire domain

Index
See Radical.

Multiplication property of inequality
If u < v and c > 0, then uc < vc. If u < and c < 0, then uc > vc

Multiplicity
The multiplicity of a zero c of a polynomial ƒ(x) of degree n > 0 is the number of times the factor (x  c) (x  z 2) Á (x  z n)

PH
The measure of acidity

Polar coordinate system
A coordinate system whose ordered pair is based on the directed distance from a central point (the pole) and the angle measured from a ray from the pole (the polar axis)

Polynomial in x
An expression that can be written in the form an x n + an1x n1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

Product of functions
(ƒg)(x) = ƒ(x)g(x)

Quartile
The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

Replication
The principle of experimental design that minimizes the effects of chance variation by repeating the experiment multiple times.

Semiperimeter of a triangle
Onehalf of the sum of the lengths of the sides of a triangle.

Standard representation of a vector
A representative arrow with its initial point at the origin

Supply curve
p = ƒ(x), where x represents production and p represents price

Transitive property
If a = b and b = c , then a = c. Similar properties hold for the inequality symbols <, >, ?, ?.

Unit vector in the direction of a vector
A unit vector that has the same direction as the given vector.

xcoordinate
The directed distance from the yaxis yzplane to a point in a plane (space), or the first number in an ordered pair (triple), pp. 12, 629.

Zero of a function
A value in the domain of a function that makes the function value zero.
