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

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

P(A or B) = P(A) + P(B) - P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)

• Bias

A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

• Bounded below

A function is bounded below if there is a number b such that b ? ƒ(x) for all x in the domain of f.

• Double-angle identity

An identity involving a trigonometric function of 2u

• equation of an ellipse

(x - h2) a2 + (y - k)2 b2 = 1 or (y - k)2 a2 + (x - h)2 b2 = 1

• Horizontal Line Test

A test for determining whether the inverse of a relation is a function.

• Index

• Intercepted arc

Arc of a circle between the initial side and terminal side of a central angle.

• Measure of an angle

The number of degrees or radians in an angle

• Nautical mile

Length of 1 minute of arc along the Earth’s equator.

• Power-reducing identity

A trigonometric identity that reduces the power to which the trigonometric functions are raised.

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

• Quartic regression

A procedure for fitting a quartic function to a set of data.

• Remainder polynomial

See Division algorithm for polynomials.

• Root of a number

See Principal nth root.

• Simple harmonic motion

Motion described by d = a sin wt or d = a cos wt

• Slant asymptote

An end behavior asymptote that is a slant line

• Unbounded interval

An interval that extends to -? or ? (or both).

• z-axis

Usually the third dimension in Cartesian space.
