Key Calculus Terms and definitions covered in this textbook
  • Back-to-back stemplot

    A stemplot with leaves on either side used to compare two distributions.

  • Compound fraction

    A fractional expression in which the numerator or denominator may contain fractions

  • Constant

    A letter or symbol that stands for a specific number,

  • Coterminal angles

    Two angles having the same initial side and the same terminal side

  • Empty set

    A set with no elements

  • Horizontal asymptote

    The line is a horizontal asymptote of the graph of a function ƒ if lim x:- q ƒ(x) = or lim x: q ƒ(x) = b

  • Horizontal Line Test

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

  • Hyperbola

    A set of points in a plane, the absolute value of the difference of whose distances from two fixed points (the foci) is a constant.

  • Integrable over [a, b] Lba

    ƒ1x2 dx exists.

  • Linear equation in x

    An equation that can be written in the form ax + b = 0, where a and b are real numbers and a Z 0

  • Lower bound of f

    Any number b for which b < ƒ(x) for all x in the domain of ƒ

  • Multiplication principle of probability

    If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(A|B) # P(B)

  • Pole

    See Polar coordinate system.

  • Power-reducing identity

    The graph in three dimensions of a seconddegree equation in three variables.

  • Statistic

    A number that measures a quantitative variable for a sample from a population.

  • Trigonometric form of a complex number

    r(cos ? + i sin ?)

  • Xmax

    The x-value of the right side of the viewing window,.

  • Zoom out

    A procedure of a graphing utility used to view more of the coordinate plane (used, for example, to find theend behavior of a function).
