Key Calculus Terms and definitions covered in this textbook
  • Aphelion

    The farthest point from the Sun in a planet’s orbit

  • Arithmetic sequence

    A sequence {an} in which an = an-1 + d for every integer n ? 2 . The number d is the common difference.

  • Bar chart

    A rectangular graphical display of categorical data.

  • Complements or complementary angles

    Two angles of positive measure whose sum is 90°

  • Dependent variable

    Variable representing the range value of a function (usually y)

  • Distance (on a number line)

    The distance between real numbers a and b, or |a - b|

  • Graph of parametric equations

    The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

  • Horizontal Line Test

    A test for determining whether the inverse of a relation is a function.

  • Inverse relation (of the relation R)

    A relation that consists of all ordered pairs b, a for which a, b belongs to R.

  • Law of cosines

    a2 = b2 + c2 - 2bc cos A, b2 = a2 + c2 - 2ac cos B, c2 = a2 + b2 - 2ab cos C

  • Linear factorization theorem

    A polynomial ƒ(x) of degree n > 0 has the factorization ƒ(x) = a(x1 - z1) 1x - i z 22 Á 1x - z n where the z1 are the zeros of ƒ

  • Local maximum

    A value ƒ(c) is a local maximum of ƒ if there is an open interval I containing c such that ƒ(x) < ƒ(c) for all values of x in I

  • nth root of unity

    A complex number v such that vn = 1

  • Objective function

    See Linear programming problem.

  • Parametrization

    A set of parametric equations for a curve.

  • PH

    The measure of acidity

  • Quantitative variable

    A variable (in statistics) that takes on numerical values for a characteristic being measured.

  • 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

  • Variable

    A letter that represents an unspecified number.

  • Window dimensions

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