Key Calculus Terms and definitions covered in this textbook
• Characteristic polynomial of a square matrix A

det(xIn - A), where A is an n x n matrix

• Correlation coefficient

A measure of the strength of the linear relationship between two variables, pp. 146, 162.

• Endpoint of an interval

A real number that represents one “end” of an interval.

• Graph of parametric equations

The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

• Instantaneous rate of change

See Derivative at x = a.

• Length of an arrow

See Magnitude of an arrow.

• Multiplication principle of counting

A principle used to find the number of ways an event can occur.

• Numerical model

A model determined by analyzing numbers or data in order to gain insight into a phenomenon, p. 64.

• Parametric curve

The graph of parametric equations.

• Piecewise-defined function

A function whose domain is divided into several parts with a different function rule applied to each part, p. 104.

• Range (in statistics)

The difference between the greatest and least values in a data set.

• Range screen

See Viewing window.

• Reflection across the x-axis

x, y and (x,-y) are reflections of each other across the x-axis.

• Removable discontinuity at x = a

lim x:a- ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

• Subtraction

a - b = a + (-b)

• System

• Unbounded interval

An interval that extends to -? or ? (or both).

• Upper bound for real zeros

A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.

• Vertical stretch or shrink

See Stretch, Shrink.
