Key Calculus Terms and definitions covered in this textbook
  • Combinatorics

    A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

  • Conversion factor

    A ratio equal to 1, used for unit conversion

  • Cosecant

    The function y = csc x

  • Domain of validity of an identity

    The set of values of the variable for which both sides of the identity are defined

  • Endpoint of an interval

    A real number that represents one “end” of an interval.

  • Extraneous solution

    Any solution of the resulting equation that is not a solution of the original equation.

  • Geometric series

    A series whose terms form a geometric sequence.

  • Inverse tangent function

    The function y = tan-1 x

  • Invertible linear system

    A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

  • Logarithmic form

    An equation written with logarithms instead of exponents

  • Median (of a data set)

    The middle number (or the mean of the two middle numbers) if the data are listed in order.

  • Multiplicity

    The multiplicity of a zero c of a polynomial ƒ(x) of degree n > 0 is the number of times the factor (x - c) (x - z 2) Á (x - z n)

  • n factorial

    For any positive integer n, n factorial is n! = n.(n - 1) . (n - 2) .... .3.2.1; zero factorial is 0! = 1

  • Negative linear correlation

    See Linear correlation.

  • Normal distribution

    A distribution of data shaped like the normal curve.

  • Opposite

    See Additive inverse of a real number and Additive inverse of a complex number.

  • Repeated zeros

    Zeros of multiplicity ? 2 (see Multiplicity).

  • Tree diagram

    A visualization of the Multiplication Principle of Probability.

  • Vertex of a cone

    See Right circular cone.

  • Weighted mean

    A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.
