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

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

Elementary row operations
The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

Equilibrium point
A point where the supply curve and demand curve intersect. The corresponding price is the equilibrium price.

Equivalent equations (inequalities)
Equations (inequalities) that have the same solutions.

Event
A subset of a sample space.

Expanded form
The right side of u(v + w) = uv + uw.

Exponential regression
A procedure for fitting an exponential function to a set of data.

Extraneous solution
Any solution of the resulting equation that is not a solution of the original equation.

Focal axis
The line through the focus and perpendicular to the directrix of a conic.

Imaginary part of a complex number
See Complex number.

Magnitude of a real number
See Absolute value of a real number

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

Normal distribution
A distribution of data shaped like the normal curve.

Ordered set
A set is ordered if it is possible to compare any two elements and say that one element is “less than” or “greater than” the other.

Power function
A function of the form ƒ(x) = k . x a, where k and a are nonzero constants. k is the constant of variation and a is the power.

Projectile motion
The movement of an object that is subject only to the force of gravity

symmetric about the xaxis
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

Unit ratio
See Conversion factor.

Velocity
A vector that specifies the motion of an object in terms of its speed and direction.
