Anchor
See Mathematical induction.

Arithmetic sequence
A sequence {an} in which an = an1 + d for every integer n ? 2 . The number d is the common difference.

Definite integral
The definite integral of the function ƒ over [a,b] is Lbaƒ(x) dx = limn: q ani=1 ƒ(xi) ¢x provided the limit of the Riemann sums exists

Descriptive statistics
The gathering and processing of numerical information

Dihedral angle
An angle formed by two intersecting planes,

Directrix of a parabola, ellipse, or hyperbola
A line used to determine the conic

Equation
A statement of equality between two expressions.

Frequency table (in statistics)
A table showing frequencies.

Lower bound of f
Any number b for which b < ƒ(x) for all x in the domain of ƒ

Main diagonal
The diagonal from the top left to the bottom right of a square matrix

Natural exponential function
The function ƒ1x2 = ex.

Observational study
A process for gathering data from a subset of a population through current or past observations. This differs from an experiment in that no treatment is imposed.

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.

Product of a scalar and a vector
The product of scalar k and vector u = 8u1, u29 1or u = 8u1, u2, u392 is k.u = 8ku1, ku291or k # u = 8ku1, ku2, ku392,

Quantitative variable
A variable (in statistics) that takes on numerical values for a characteristic being measured.

Resistant measure
A statistical measure that does not change much in response to outliers.

Sample standard deviation
The standard deviation computed using only a sample of the entire population.

Seconddegree equation in two variables
Ax 2 + Bxy + Cy2 + Dx + Ey + F = 0, where A, B, and C are not all zero.

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

Vertical asymptote
The line x = a is a vertical asymptote of the graph of the function ƒ if limx:a+ ƒ1x2 = q or lim x:a ƒ1x2 = q.
