Key Calculus Terms and definitions covered in this textbook
• Basic logistic function

The function ƒ(x) = 1 / 1 + e-x

• 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.

• Causation

A relationship between two variables in which the values of the response variable are directly affected by the values of the explanatory variable

• Closed interval

An interval that includes its endpoints

• Combination

An arrangement of elements of a set, in which order is not important

• Component form of a vector

If a vector’s representative in standard position has a terminal point (a,b) (or (a, b, c)) , then (a,b) (or (a, b, c)) is the component form of the vector, and a and b are the horizontal and vertical components of the vector (or a, b, and c are the x-, y-, and z-components of the vector, respectively)

• Data

Facts collected for statistical purposes (singular form is datum)

• Exponential form

An equation written with exponents instead of logarithms.

• Exponential function

A function of the form ƒ(x) = a ? bx,where ?0, b > 0 b ?1

• Finite series

Sum of a finite number of terms.

• Graph of a function ƒ

The set of all points in the coordinate plane corresponding to the pairs (x, ƒ(x)) for x in the domain of ƒ.

• Inverse of a matrix

The inverse of a square matrix A, if it exists, is a matrix B, such that AB = BA = I , where I is an identity matrix.

• Local maximum

A value ƒ(c) is a local maximum of ƒ if there is an open interval I containing c such that ƒ(x) < ƒ(c) for all values of x in I

• Minute

Angle measure equal to 1/60 of a degree.

• Odd-even identity

For a basic trigonometric function f, an identity relating f(x) to f(-x).

• Partial fraction decomposition

See Partial fractions.

• Polynomial interpolation

The process of fitting a polynomial of degree n to (n + 1) points.

• Repeated zeros

Zeros of multiplicity ? 2 (see Multiplicity).

• Statute mile

5280 feet.

• Weights

See Weighted mean.
