Key Calculus Terms and definitions covered in this textbook
  • Absolute minimum

    A value ƒ(c) is an absolute minimum value of ƒ if ƒ(c) ? ƒ(x)for all x in the domain of ƒ.

  • Absolute value of a complex number

    The absolute value of the complex number z = a + b is given by ?a2+b2; also, the length of the segment from the origin to z in the complex plane.

  • Acute angle

    An angle whose measure is between 0° and 90°

  • 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.

  • Center

    The central point in a circle, ellipse, hyperbola, or sphere

  • Closed interval

    An interval that includes its endpoints

  • Expanded form

    The right side of u(v + w) = uv + uw.

  • Geometric sequence

    A sequence {an}in which an = an-1.r for every positive integer n ? 2. The nonzero number r is called the common ratio.

  • Imaginary axis

    See Complex plane.

  • nth root of a complex number z

    A complex number v such that vn = z

  • Parametric equations

    Equations of the form x = ƒ(t) and y = g(t) for all t in an interval I. The variable t is the parameter and I is the parameter interval.

  • Quotient polynomial

    See Division algorithm for polynomials.

  • Rational expression

    An expression that can be written as a ratio of two polynomials.

  • Relevant domain

    The portion of the domain applicable to the situation being modeled.

  • Resolving a vector

    Finding the horizontal and vertical components of a vector.

  • Synthetic division

    A procedure used to divide a polynomial by a linear factor, x - a

  • System

    A set of equations or inequalities.

  • Transformation

    A function that maps real numbers to real numbers.

  • Vertex of a cone

    See Right circular cone.

  • x-coordinate

    The directed distance from the y-axis yz-plane to a point in a plane (space), or the first number in an ordered pair (triple), pp. 12, 629.
