Bounded
A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

Combinatorics
A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

Convergence of a series
A series aqk=1 ak converges to a sum S if imn: q ank=1ak = S

Divisor of a polynomial
See Division algorithm for polynomials.

Length of a vector
See Magnitude of a vector.

Median (of a data set)
The middle number (or the mean of the two middle numbers) if the data are listed in order.

Minor axis
The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

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

Numerical model
A model determined by analyzing numbers or data in order to gain insight into a phenomenon, p. 64.

Oddeven identity
For a basic trigonometric function f, an identity relating f(x) to f(x).

Onetoone function
A function in which each element of the range corresponds to exactly one element in the domain

Parametric equations for a line in space
The line through P0(x 0, y0, z 0) in the direction of the nonzero vector v = <a, b, c> has parametric equations x = x 0 + at, y = y 0 + bt, z = z0 + ct.

Principal nth root
If bn = a, then b is an nth root of a. If bn = a and a and b have the same sign, b is the principal nth root of a (see Radical), p. 508.

Rational zeros
Zeros of a function that are rational numbers.

Resistant measure
A statistical measure that does not change much in response to outliers.

Scientific notation
A positive number written as c x 10m, where 1 ? c < 10 and m is an integer.

Shrink of factor c
A transformation of a graph obtained by multiplying all the xcoordinates (horizontal shrink) by the constant 1/c or all of the ycoordinates (vertical shrink) by the constant c, 0 < c < 1.

Speed
The magnitude of the velocity vector, given by distance/time.

Standard form: equation of a circle
(x  h)2 + (y  k2) = r 2

Zero matrix
A matrix consisting entirely of zeros.
