Key Calculus Terms and definitions covered in this textbook
• Anchor

See Mathematical induction.

• Bounded

A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

• Characteristic polynomial of a square matrix A

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

• Confounding variable

A third variable that affects either of two variables being studied, making inferences about causation unreliable

• Difference of complex numbers

(a + bi) - (c + di) = (a - c) + (b - d)i

• Factored form

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

• Inequality

A statement that compares two quantities using an inequality symbol

• Inverse cosecant function

The function y = csc-1 x

• Inverse variation

See Power function.

• Perpendicular lines

Two lines that are at right angles to each other

An angle in standard position whose terminal side lies on an axis.

• Rational numbers

Numbers that can be written as a/b, where a and b are integers, and b ? 0.

• Resistant measure

A statistical measure that does not change much in response to outliers.

• Rigid transformation

A transformation that leaves the basic shape of a graph unchanged.

• Row operations

See Elementary row operations.

• Second-degree equation in two variables

Ax 2 + Bxy + Cy2 + Dx + Ey + F = 0, where A, B, and C are not all zero.

• Semiminor axis

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

• Slope-intercept form (of a line)

y = mx + b

• Solution set of an inequality
