Key Calculus Terms and definitions covered in this textbook
• Angular speed

Speed of rotation, typically measured in radians or revolutions per unit time

• Arctangent function

See Inverse tangent function.

• Composition of functions

(f ? g) (x) = f (g(x))

• Continuous at x = a

lim x:a x a ƒ(x) = ƒ(a)

• Convenience sample

A sample that sacrifices randomness for convenience

• Equal matrices

Matrices that have the same order and equal corresponding elements.

• Factor

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

• Implicitly defined function

A function that is a subset of a relation defined by an equation in x and y.

• Inductive step

See Mathematical induction.

• Nautical mile

Length of 1 minute of arc along the Earth’s equator.

• Negative linear correlation

See Linear correlation.

• Orthogonal vectors

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

• Pascal’s triangle

A number pattern in which row n (beginning with n = 02) consists of the coefficients of the expanded form of (a+b)n.

• Polynomial in x

An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

• Random variable

A function that assigns real-number values to the outcomes in a sample space.

• Reciprocal identity

An identity that equates a trigonometric function with the reciprocal of another trigonometricfunction.

• Replication

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

• 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.

A graph in which (-x, -y) is on the the graph whenever (x, y) is; or a graph in which (-r, ?) or (r, ? + ?) is on the graph whenever (r, ?) is

• Yscl

The scale of the tick marks on the y-axis in a viewing window.
