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.

• Chord of a conic

A line segment with endpoints on the conic

• Compounded annually

See Compounded k times per year.

• Compounded k times per year

Interest compounded using the formula A = Pa1 + rkbkt where k = 1 is compounded annually, k = 4 is compounded quarterly k = 12 is compounded monthly, etc.

• Conditional probability

The probability of an event A given that an event B has already occurred

• 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

• Demand curve

p = g(x), where x represents demand and p represents price

• Half-angle identity

Identity involving a trigonometric function of u/2.

• Implied domain

The domain of a function’s algebraic expression.

• Initial value of a function

ƒ 0.

• Instantaneous velocity

The instantaneous rate of change of a position function with respect to time, p. 737.

• Jump discontinuity at x a

limx:a - ƒ1x2 and limx:a + ƒ1x2 exist but are not equal

• Midpoint (on a number line)

For the line segment with endpoints a and b, a + b2

• Open interval

An interval that does not include its endpoints.

• Probability distribution

The collection of probabilities of outcomes in a sample space assigned by a probability function.

• Pythagorean identities

sin2 u + cos2 u = 1, 1 + tan2 u = sec2 u, and 1 + cot2 u = csc2 u

An equation that can be written in the form ax 2 + bx + c = 01a ? 02
