Key Calculus Terms and definitions covered in this textbook
  • Algebraic model

    An equation that relates variable quantities associated with phenomena being studied

  • Arctangent function

    See Inverse tangent function.

  • Binomial

    A polynomial with exactly two terms

  • Combinations of n objects taken r at a time

    There are nCr = n! r!1n - r2! such combinations,

  • Continuous function

    A function that is continuous on its entire domain

  • Distributive property

    a(b + c) = ab + ac and related properties

  • Domain of validity of an identity

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

  • equation of a parabola

    (x - h)2 = 4p(y - k) or (y - k)2 = 4p(x - h)

  • Implicitly defined function

    A function that is a subset of a relation defined by an equation in x and y.

  • Inverse of a matrix

    The inverse of a square matrix A, if it exists, is a matrix B, such that AB = BA = I , where I is an identity matrix.

  • Matrix, m x n

    A rectangular array of m rows and n columns of real numbers

  • Numerical derivative of ƒ at a

    NDER f(a) = ƒ1a + 0.0012 - ƒ1a - 0.00120.002

  • Probability distribution

  • Regression model

    An equation found by regression and which can be used to predict unknown values.

  • Right circular cone

    The surface created when a line is rotated about a second line that intersects but is not perpendicular to the first line.

  • Row echelon form

    A matrix in which rows consisting of all 0’s occur only at the bottom of the matrix, the first nonzero entry in any row with nonzero entries is 1, and the leading 1’s move to the right as we move down the rows.

  • Sum identity

    An identity involving a trigonometric function of u + v

  • Window dimensions

    The restrictions on x and y that specify a viewing window. See Viewing window.

  • Xmax

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

  • Zero of a function

    A value in the domain of a function that makes the function value zero.
