Coefficient of determination
The number r2 or R2 that measures how well a regression curve fits the data

Direction of an arrow
The angle the arrow makes with the positive xaxis

Feasible points
Points that satisfy the constraints in a linear programming problem.

First octant
The points (x, y, z) in space with x > 0 y > 0, and z > 0.

Graph of a relation
The set of all points in the coordinate plane corresponding to the ordered pairs of the relation.

Independent variable
Variable representing the domain value of a function (usually x).

Integrable over [a, b] Lba
ƒ1x2 dx exists.

Jump discontinuity at x a
limx:a  ƒ1x2 and limx:a + ƒ1x2 exist but are not equal

Logistic regression
A procedure for fitting a logistic curve to a set of data

Mapping
A function viewed as a mapping of the elements of the domain onto the elements of the range

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.

Normal curve
The graph of ƒ(x) = ex2/2

Order of an m x n matrix
The order of an m x n matrix is m x n.

Quadratic equation in x
An equation that can be written in the form ax 2 + bx + c = 01a ? 02

Reciprocal function
The function ƒ(x) = 1x

Slant line
A line that is neither horizontal nor vertical

Symmetric about the yaxis
A graph in which (x, y) is on the graph whenever (x, y) is; or a graph in which (r, ?) or (r, ?, ?) is on the graph whenever (r, ?) is

Vertical asymptote
The line x = a is a vertical asymptote of the graph of the function ƒ if limx:a+ ƒ1x2 = q or lim x:a ƒ1x2 = q.

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.
