Acute angle
An angle whose measure is between 0° and 90°

Angle
Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

Causation
A relationship between two variables in which the values of the response variable are directly affected by the values of the explanatory variable

Composition of functions
(f ? g) (x) = f (g(x))

Descriptive statistics
The gathering and processing of numerical information

Histogram
A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

Leading term
See Polynomial function in x.

Line of symmetry
A line over which a graph is the mirror image of itself

Logarithmic regression
See Natural logarithmic regression

nth root of a complex number z
A complex number v such that vn = z

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.

Quadric surface
The graph in three dimensions of a seconddegree equation in three variables.

Range screen
See Viewing window.

Reflection through the origin
x, y and (x,y) are reflections of each other through the origin.

Statistic
A number that measures a quantitative variable for a sample from a population.

Symmetric matrix
A matrix A = [aij] with the property aij = aji for all i and j

Upper bound for real zeros
A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.

Venn diagram
A visualization of the relationships among events within a sample space.

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 factorial
See n factorial.
