Key Calculus Terms and definitions covered in this textbook
• Commutative properties

a + b = b + a ab = ba

• 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)

• Convenience sample

A sample that sacrifices randomness for convenience

• Cosine

The function y = cos x

• Equal complex numbers

Complex numbers whose real parts are equal and whose imaginary parts are equal.

• Even function

A function whose graph is symmetric about the y-axis for all x in the domain of ƒ.

• Finite series

Sum of a finite number of terms.

• Identity properties

a + 0 = a, a ? 1 = a

• Increasing on an interval

A function ƒ is increasing on an interval I if, for any two points in I, a positive change in x results in a positive change in.

• Integers

The numbers . . ., -3, -2, -1, 0,1,2,...2

• 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.

• Logarithmic re-expression of data

Transformation of a data set involving the natural logarithm: exponential regression, natural logarithmic regression, power regression

• Logistic growth function

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

• NDER ƒ(a)

See Numerical derivative of ƒ at x = a.

• Permutation

An arrangement of elements of a set, in which order is important.

• Probability simulation

A numerical simulation of a probability experiment in which assigned numbers appear with the same probabilities as the outcomes of the experiment.

• Real zeros

Zeros of a function that are real numbers.

• Second quartile

See Quartile.

• System

A set of equations or inequalities.

• xy-plane

The points x, y, 0 in Cartesian space.
