Key Calculus Terms and definitions covered in this textbook
• Average rate of change of ƒ over [a, b]

The number ƒ(b) - ƒ(a) b - a, provided a ? b.

• Distance (on a number line)

The distance between real numbers a and b, or |a - b|

• End behavior asymptote of a rational function

A polynomial that the function approaches as.

• Factor

In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

• Geometric sequence

A sequence {an}in which an = an-1.r for every positive integer n ? 2. The nonzero number r is called the common ratio.

• Graph of an inequality in x and y

The set of all points in the coordinate plane corresponding to the solutions x, y of the inequality.

• Hypotenuse

Side opposite the right angle in a right triangle.

• Imaginary part of a complex number

See Complex number.

• Inductive step

See Mathematical induction.

• Inverse sine function

The function y = sin-1 x

• Line of travel

The path along which an object travels

• Major axis

The line segment through the foci of an ellipse with endpoints on the ellipse

• Multiplicity

The multiplicity of a zero c of a polynomial ƒ(x) of degree n > 0 is the number of times the factor (x - c) (x - z 2) Á (x - z n)

• Ordered pair

A pair of real numbers (x, y), p. 12.

• Product of matrices A and B

The matrix in which each entry is obtained by multiplying the entries of a row of A by the corresponding entries of a column of B and then adding

• Projectile motion

The movement of an object that is subject only to the force of gravity

• Rational zeros

Zeros of a function that are rational numbers.

• Series

A finite or infinite sum of terms.

• Transformation

A function that maps real numbers to real numbers.

• Zero factor property

If ab = 0 , then either a = 0 or b = 0.
