Absolute maximum
A value ƒ(c) is an absolute maximum value of ƒ if ƒ(c) ? ƒ(x) for all x in the domain of ƒ.

Algebraic expression
A combination of variables and constants involving addition, subtraction, multiplication, division, powers, and roots

Census
An observational study that gathers data from an entire population

De Moivre’s theorem
(r(cos ? + i sin ?))n = r n (cos n? + i sin n?)

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

Graph of parametric equations
The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

Inductive step
See Mathematical induction.

Irrational zeros
Zeros of a function that are irrational numbers.

Linear equation in x
An equation that can be written in the form ax + b = 0, where a and b are real numbers and a Z 0

Major axis
The line segment through the foci of an ellipse with endpoints on the ellipse

Opens upward or downward
A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

Periodic function
A function ƒ for which there is a positive number c such that for every value t in the domain of ƒ. The smallest such number c is the period of the function.

Placebo
In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

Probability distribution
The collection of probabilities of outcomes in a sample space assigned by a probability function.

Random variable
