Key Calculus Terms and definitions covered in this textbook
• Absolute minimum

A value ƒ(c) is an absolute minimum value of ƒ if ƒ(c) ? ƒ(x)for all x in the domain of ƒ.

• Angular speed

Speed of rotation, typically measured in radians or revolutions per unit time

• 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.

• Complex fraction

See Compound fraction.

• Conjugate axis of a hyperbola

The line segment of length 2b that is perpendicular to the focal axis and has the center of the hyperbola as its midpoint

• Damping factor

The factor Ae-a in an equation such as y = Ae-at cos bt

• Data

Facts collected for statistical purposes (singular form is datum)

• Directrix of a parabola, ellipse, or hyperbola

A line used to determine the conic

• Double-angle identity

An identity involving a trigonometric function of 2u

• Interval

Connected subset of the real number line with at least two points, p. 4.

• Objective function

See Linear programming problem.

• Open interval

An interval that does not include its endpoints.

• Partial fractions

The process of expanding a fraction into a sum of fractions. The sum is called the partial fraction decomposition of the original fraction.

• Pythagorean

Theorem In a right triangle with sides a and b and hypotenuse c, c2 = a2 + b2

• Quotient identities

tan ?= sin ?cos ?and cot ?= cos ? sin ?

• Right-hand limit of ƒ at x a

The limit of ƒ as x approaches a from the right.

• Series

A finite or infinite sum of terms.

• Standard representation of a vector

A representative arrow with its initial point at the origin

• Sum of a finite arithmetic series

Sn = na a1 + a2 2 b = n 2 32a1 + 1n - 12d4,

• Symmetric property of equality

If a = b, then b = a
