Key Calculus Terms and definitions covered in this textbook
  • Absolute value of a real number

    Denoted by |a|, represents the number a or the positive number -a if a < 0.

  • Binomial

    A polynomial with exactly two terms

  • 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.

  • Coterminal angles

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

  • Deductive reasoning

    The process of utilizing general information to prove a specific hypothesis

  • Elimination method

    A method of solving a system of linear equations

  • Fitting a line or curve to data

    Finding a line or curve that comes close to passing through all the points in a scatter plot.

  • Length of an arrow

    See Magnitude of an arrow.

  • Limit at infinity

    limx: qƒ1x2 = L means that ƒ1x2 gets arbitrarily close to L as x gets arbitrarily large; lim x:- q ƒ1x2 means that gets arbitrarily close to L as gets arbitrarily large

  • Numerical derivative of ƒ at a

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

  • Piecewise-defined function

    A function whose domain is divided into several parts with a different function rule applied to each part, p. 104.

  • Product of functions

    (ƒg)(x) = ƒ(x)g(x)

  • Quartic function

    A degree 4 polynomial function.

  • Richter scale

    A logarithmic scale used in measuring the intensity of an earthquake.

  • Sphere

    A set of points in Cartesian space equally distant from a fixed point called the center.

  • Sum of complex numbers

    (a + bi) + (c + di) = (a + c) + (b + d)i

  • Summation notation

    The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

  • Unbounded interval

    An interval that extends to -? or ? (or both).

  • Vertex of an angle

    See Angle.

  • xy-plane

    The points x, y, 0 in Cartesian space.
