Additive inverse of a real number
The opposite of b , or b

Categorical variable
In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

Compound interest
Interest that becomes part of the investment

Confounding variable
A third variable that affects either of two variables being studied, making inferences about causation unreliable

Doubleangle identity
An identity involving a trigonometric function of 2u

equation of a hyperbola
(x  h)2 a2  (y  k)2 b2 = 1 or (y  k)2 a2  (x  h)2 b2 = 1

equation of a parabola
(x  h)2 = 4p(y  k) or (y  k)2 = 4p(x  h)

Graph of a function ƒ
The set of all points in the coordinate plane corresponding to the pairs (x, ƒ(x)) for x in the domain of ƒ.

Mean (of a set of data)
The sum of all the data divided by the total number of items

If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(AB) # P(B)

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

Ordered pair
A pair of real numbers (x, y), p. 12.

Product of matrices A and B
The matrix in which each entry is obtained by multiplying the entries of a row of A by the corresponding entries of a column of B and then adding

Reciprocal function
The function ƒ(x) = 1x

Rectangular coordinate system
See Cartesian coordinate system.

Recursively defined sequence
A sequence defined by giving the first term (or the first few terms) along with a procedure for finding the subsequent terms.

Reference angle
See Reference triangle

RRAM
A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the righthand end point of each subinterval.
