Key Calculus Terms and definitions covered in this textbook
• Arctangent function

See Inverse tangent function.

• Bar chart

A rectangular graphical display of categorical data.

• Bias

A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

• Event

A subset of a sample space.

• Index

• 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)

• Magnitude of an arrow

The magnitude of PQ is the distance between P and Q

• Mapping

A function viewed as a mapping of the elements of the domain onto the elements of the range

• Mathematical induction

A process for proving that a statement is true for all natural numbers n by showing that it is true for n = 1 (the anchor) and that, if it is true for n = k, then it must be true for n = k + 1 (the inductive step)

• NDER ƒ(a)

See Numerical derivative of ƒ at x = a.

• Product rule of logarithms

ogb 1RS2 = logb R + logb S, R > 0, S > 0,

• Richter scale

A logarithmic scale used in measuring the intensity of an earthquake.

• Row operations

See Elementary row operations.

• Standard deviation

A measure of how a data set is spread

• Statute mile

5280 feet.

• Sum of two vectors

<u1, u2> + <v1, v2> = <u1 + v1, u2 + v2> <u1 + v1, u2 + v2, u3 + v3>

• Supply curve

p = ƒ(x), where x represents production and p represents price

• Time plot

A line graph in which time is measured on the horizontal axis.

• Triangular form

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

• Vertex of a parabola

The point of intersection of a parabola and its line of symmetry.
