Key Calculus Terms and definitions covered in this textbook
• Arc length formula

The length of an arc in a circle of radius r intercepted by a central angle of u radians is s = r u.

• Back-to-back stemplot

A stemplot with leaves on either side used to compare two distributions.

• Distance (in Cartesian space)

The distance d(P, Q) between and P(x, y, z) and Q(x, y, z) or d(P, Q) ((x ) - x 2)2 + (y1 - y2)2 + (z 1 - z 2)2

• Expanded form

The right side of u(v + w) = uv + uw.

• Explicitly defined sequence

A sequence in which the kth term is given as a function of k.

• Grapher or graphing utility

Graphing calculator or a computer with graphing software.

• Identity properties

a + 0 = a, a ? 1 = a

• Inverse variation

See Power function.

• LRAM

A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the left-hand endpoint of each subinterval

• n factorial

For any positive integer n, n factorial is n! = n.(n - 1) . (n - 2) .... .3.2.1; zero factorial is 0! = 1

• nth root of a complex number z

A complex number v such that vn = z

• Open interval

An interval that does not include its endpoints.

• Partial sums

See Sequence of partial sums.

• Randomization

The principle of experimental design that makes it possible to use the laws of probability when making inferences.

• Regression model

An equation found by regression and which can be used to predict unknown values.

• Richter scale

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

• Semimajor axis

The distance from the center to a vertex of an ellipse.

• Semiminor axis

The distance from the center of an ellipse to a point on the ellipse along a line perpendicular to the major axis.

• Summation notation

The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

• 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.
