Coefficient
The real number multiplied by the variable(s) in a polynomial term

Combination
An arrangement of elements of a set, in which order is not important

Combinations of n objects taken r at a time
There are nCr = n! r!1n  r2! such combinations,

Convenience sample
A sample that sacrifices randomness for convenience

Direction angle of a vector
The angle that the vector makes with the positive xaxis

Equally likely outcomes
Outcomes of an experiment that have the same probability of occurring.

Exponential decay function
Decay modeled by ƒ(x) = a ? bx, a > 0 with 0 < b < 1.

Graph of a polar equation
The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

Index
See Radical.

Lower bound of f
Any number b for which b < ƒ(x) for all x in the domain of ƒ

Negative angle
Angle generated by clockwise rotation.

Order of magnitude (of n)
log n.

Polar coordinates
The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

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)

Probability simulation
A numerical simulation of a probability experiment in which assigned numbers appear with the same probabilities as the outcomes of the experiment.

Real axis
See Complex plane.

Sine
The function y = sin x.

Solution of a system in two variables
An ordered pair of real numbers that satisfies all of the equations or inequalities in the system

Standard form of a complex number
a + bi, where a and b are real numbers

Weighted mean
A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.
