Key Calculus Terms and definitions covered in this textbook
• Algebraic model

An equation that relates variable quantities associated with phenomena being studied

• 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.

• Categorical variable

In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

• Center

The central point in a circle, ellipse, hyperbola, or sphere

• Control

The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

• Eccentricity

A nonnegative number that specifies how off-center the focus of a conic is

• Factor

In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

• Inverse reflection principle

If the graph of a relation is reflected across the line y = x , the graph of the inverse relation results.

• Law of sines

sin A a = sin B b = sin C c

• Linear programming problem

A method of solving certain problems involving maximizing or minimizing a function of two variables (called an objective function) subject to restrictions (called constraints)

• Parameter interval

See Parametric equations.

• Plane in Cartesian space

The graph of Ax + By + Cz + D = 0, where A, B, and C are not all zero.

• Quotient identities

tan ?= sin ?cos ?and cot ?= cos ? sin ?

• Re-expression of data

A transformation of a data set.

• Replication

The principle of experimental design that minimizes the effects of chance variation by repeating the experiment multiple times.

• Sample survey

A process for gathering data from a subset of a population, usually through direct questioning.

• Solution of a system in two variables

An ordered pair of real numbers that satisfies all of the equations or inequalities in the system

• Unbounded interval

An interval that extends to -? or ? (or both).

• Unit vector in the direction of a vector

A unit vector that has the same direction as the given vector.

• x-axis

Usually the horizontal coordinate line in a Cartesian coordinate system with positive direction to the right,.
