nth root, where n = 3 (see Principal nth root),

• Distance (on a number line)

The distance between real numbers a and b, or |a - b|

• equation of a quadratic function

ƒ(x) = ax 2 + bx + c(a ? 0)

• Fitting a line or curve to data

Finding a line or curve that comes close to passing through all the points in a scatter plot.

• Geometric series

A series whose terms form a geometric sequence.

• Half-angle identity

Identity involving a trigonometric function of u/2.

• Index

• Linear inequality in x

An inequality that can be written in the form ax + b < 0 ,ax + b … 0 , ax + b > 0, or ax + b Ú 0, where a and b are real numbers and a Z 0

• Linear regression line

The line for which the sum of the squares of the residuals is the smallest possible

• Measure of center

A measure of the typical, middle, or average value for a data set

• Midpoint (in Cartesian space)

For the line segment with endpoints (x 1, y1, z 1) and (x2, y2, z2), ax 1 + x 22 ,y1 + y22 ,z 1 + z 22 b

• Multiplicative inverse of a real number

The reciprocal of b, or 1/b, b Z 0

• Negative association

A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

• Randomization

The principle of experimental design that makes it possible to use the laws of probability when making inferences.

• Rational numbers

Numbers that can be written as a/b, where a and b are integers, and b ? 0.

• Reference angle

See Reference triangle

• Reference triangle

For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

• Whole numbers

The numbers 0, 1, 2, 3, ... .
