Key Calculus Terms and definitions covered in this textbook
  • Addition principle of probability.

    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)

  • Argument of a complex number

    The argument of a + bi is the direction angle of the vector {a,b}.

  • Base

    See Exponential function, Logarithmic function, nth power of a.

  • Boxplot (or box-and-whisker plot)

    A graph that displays a five-number summary

  • Categorical variable

    In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

  • Coefficient of determination

    The number r2 or R2 that measures how well a regression curve fits the data

  • Coordinate(s) of a point

    The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian three-dimensional space

  • Direct variation

    See Power function.

  • Expanded form of a series

    A series written explicitly as a sum of terms (not in summation notation).

  • 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

  • Order of an m x n matrix

    The order of an m x n matrix is m x n.

  • Pythagorean identities

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

  • Reflexive property of equality

    a = a

  • Right angle

    A 90° angle.

  • Secant

    The function y = sec x.

  • Speed

    The magnitude of the velocity vector, given by distance/time.

  • Standard form: equation of a circle

    (x - h)2 + (y - k2) = r 2

  • Sum of an infinite geometric series

    Sn = a 1 - r , |r| 6 1

  • Upper bound for ƒ

    Any number B for which ƒ(x) ? B for all x in the domain of ƒ.

  • y-axis

    Usually the vertical coordinate line in a Cartesian coordinate system with positive direction up, pp. 12, 629.
