Absolute value of a complex number
The absolute value of the complex number z = a + b is given by ?a2+b2; also, the length of the segment from the origin to z in the complex plane.

Boundary
The set of points on the “edge” of a region

Bounded below
A function is bounded below if there is a number b such that b ? ƒ(x) 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

Cubic
A degree 3 polynomial function

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

Even function
A function whose graph is symmetric about the yaxis for all x in the domain of ƒ.

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

Horizontal line
y = b.

Line of symmetry
A line over which a graph is the mirror image of itself

NDER ƒ(a)
See Numerical derivative of ƒ at x = a.

Quotient rule of logarithms
logb a R S b = logb R  logb S, R > 0, S > 0

Right circular cone
The surface created when a line is rotated about a second line that intersects but is not perpendicular to the first line.

Rose curve
A graph of a polar equation or r = a cos nu.

Row operations
See Elementary row operations.

Scatter plot
A plot of all the ordered pairs of a twovariable data set on a coordinate plane.

Solution of an equation or inequality
A value of the variable (or values of the variables) for which the equation or inequality is true

Standard position (angle)
An angle positioned on a rectangular coordinate system with its vertex at the origin and its initial side on the positive xaxis

Statistic
A number that measures a quantitative variable for a sample from a population.

Venn diagram
A visualization of the relationships among events within a sample space.
