Key Calculus Terms and definitions covered in this textbook
  • Bounded

    A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

  • 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

  • Convergence of a series

    A series aqk=1 ak converges to a sum S if imn: q ank=1ak = S

  • Divisor of a polynomial

    See Division algorithm for polynomials.

  • Length of a vector

    See Magnitude of a vector.

  • Median (of a data set)

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

  • Minor axis

    The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

  • Multiplication property of inequality

    If u < v and c > 0, then uc < vc. If u < and c < 0, then uc > vc

  • Numerical model

    A model determined by analyzing numbers or data in order to gain insight into a phenomenon, p. 64.

  • Odd-even identity

    For a basic trigonometric function f, an identity relating f(x) to f(-x).

  • One-to-one function

    A function in which each element of the range corresponds to exactly one element in the domain

  • Parametric equations for a line in space

    The line through P0(x 0, y0, z 0) in the direction of the nonzero vector v = <a, b, c> has parametric equations x = x 0 + at, y = y 0 + bt, z = z0 + ct.

  • Principal nth root

    If bn = a, then b is an nth root of a. If bn = a and a and b have the same sign, b is the principal nth root of a (see Radical), p. 508.

  • Rational zeros

    Zeros of a function that are rational numbers.

  • Resistant measure

    A statistical measure that does not change much in response to outliers.

  • Scientific notation

    A positive number written as c x 10m, where 1 ? c < 10 and m is an integer.

  • Shrink of factor c

    A transformation of a graph obtained by multiplying all the x-coordinates (horizontal shrink) by the constant 1/c or all of the y-coordinates (vertical shrink) by the constant c, 0 < c < 1.

  • Speed

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

  • Standard form: equation of a circle

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

  • Zero matrix

    A matrix consisting entirely of zeros.
