Key Calculus Terms and definitions covered in this textbook
• Constant function (on an interval)

ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

• Descriptive statistics

The gathering and processing of numerical information

• Direction vector for a line

A vector in the direction of a line in three-dimensional space

• Even function

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

• Inverse cosine function

The function y = cos-1 x

• Inverse properties

a + 1-a2 = 0, a # 1a

• Linear correlation

A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

• Linear function

A function that can be written in the form ƒ(x) = mx + b, where and b are real numbers

• One-to-one rule of logarithms

x = y if and only if logb x = logb y.

• Product of functions

(ƒg)(x) = ƒ(x)g(x)

• Quantitative variable

A variable (in statistics) that takes on numerical values for a characteristic being measured.

• Sample standard deviation

The standard deviation computed using only a sample of the entire population.

• Solve algebraically

Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

• Symmetric matrix

A matrix A = [aij] with the property aij = aji for all i and j

• Triangular form

A special form for a system of linear equations that facilitates finding the solution.

• Triangular number

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

• Variance

The square of the standard deviation.

• Vertical translation

A shift of a graph up or down.

• Work

The product of a force applied to an object over a given distance W = ƒFƒ ƒAB!ƒ.

• Xscl

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