Bounded
A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

Complex plane
A coordinate plane used to represent the complex numbers. The xaxis of the complex plane is called the real axis and the yaxis is the imaginary axis

Constant term
See Polynomial function

Damping factor
The factor Aea in an equation such as y = Aeat cos bt

Dot product
The number found when the corresponding components of two vectors are multiplied and then summed

Exponent
See nth power of a.

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

Halfplane
The graph of the linear inequality y ? ax + b, y > ax + b y ? ax + b, or y < ax + b.

Initial side of an angle
See Angle.

Instantaneous rate of change
See Derivative at x = a.

Multiplication principle of probability
If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(AB) # P(B)

Sinusoidal regression
A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

Solution set of an inequality
The set of all solutions of an inequality

Solve algebraically
Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

Standard form of a polynomial function
ƒ(x) = an x n + an1x n1 + Á + a1x + a0

Sum of complex numbers
(a + bi) + (c + di) = (a + c) + (b + d)i

Tangent line of ƒ at x = a
The line through (a, ƒ(a)) with slope ƒ'(a) provided ƒ'(a) exists.

Unit vector
Vector of length 1.

Vector
An ordered pair <a, b> of real numbers in the plane, or an ordered triple <a, b, c> of real numbers in space. A vector has both magnitude and direction.

Vertical line test
A test for determining whether a graph is a function.
