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

    An equation that relates variable quantities associated with phenomena being studied

  • Bearing

    Measure of the clockwise angle that the line of travel makes with due north

  • Equal complex numbers

    Complex numbers whose real parts are equal and whose imaginary parts are equal.

  • Half-life

    The amount of time required for half of a radioactive substance to decay.

  • Heron’s formula

    The area of ¢ABC with semiperimeter s is given by 2s1s - a21s - b21s - c2.

  • Imaginary axis

    See Complex plane.

  • Intercepted arc

    Arc of a circle between the initial side and terminal side of a central angle.

  • Negative association

    A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

  • Odd function

    A function whose graph is symmetric about the origin (ƒ(-x) = -ƒ(x) for all x in the domain of f).

  • One-to-one rule of exponents

    x = y if and only if bx = by.

  • Parallel lines

    Two lines that are both vertical or have equal slopes.

  • Quadric surface

    The graph in three dimensions of a seconddegree equation in three variables.

  • Quotient of functions

    a ƒ g b(x) = ƒ(x) g(x) , g(x) ? 0

  • Radicand

    See Radical.

  • Regression model

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

  • Repeated zeros

    Zeros of multiplicity ? 2 (see Multiplicity).

  • Scientific notation

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

  • Statute mile

    5280 feet.

  • Vector

    An ordered pair <a, b> of real numbers in the plane, or an ordered triple <a, b, c> of real numbers in space. A vector has both magnitude and direction.

  • yz-plane

    The points (0, y, z) in Cartesian space.
