Angle of depression
The acute angle formed by the line of sight (downward) and the horizontal

Commutative properties
a + b = b + a ab = ba

Compounded monthly
See Compounded k times per year.

Derivative of ƒ
The function defined by ƒ'(x) = limh:0ƒ(x + h)  ƒ(x)h for all of x where the limit exists

equation of an ellipse
(x  h2) a2 + (y  k)2 b2 = 1 or (y  k)2 a2 + (x  h)2 b2 = 1

Geometric sequence
A sequence {an}in which an = an1.r for every positive integer n ? 2. The nonzero number r is called the common ratio.

Graphical model
A visible representation of a numerical or algebraic model.

Hyperboloid of revolution
A surface generated by rotating a hyperbola about its transverse axis, p. 607.

Leibniz notation
The notation dy/dx for the derivative of ƒ.

Logarithmic function with base b
The inverse of the exponential function y = bx, denoted by y = logb x

Logistic growth function
A model of population growth: ƒ1x2 = c 1 + a # bx or ƒ1x2 = c1 + aekx, where a, b, c, and k are positive with b < 1. c is the limit to growth

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

Midpoint (in Cartesian space)
For the line segment with endpoints (x 1, y1, z 1) and (x2, y2, z2), ax 1 + x 22 ,y1 + y22 ,z 1 + z 22 b

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.

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.

Orthogonal vectors
Two vectors u and v with u x v = 0.

Outliers
Data items more than 1.5 times the IQR below the first quartile or above the third quartile.

Principal nth root
If bn = a, then b is an nth root of a. If bn = a and a and b have the same sign, b is the principal nth root of a (see Radical), p. 508.

Product rule of logarithms
ogb 1RS2 = logb R + logb S, R > 0, S > 0,

Triangular number
A number that is a sum of the arithmetic series 1 + 2 + 3 + ... + n for some natural number n.
