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

    An equation that relates variable quantities associated with phenomena being studied

  • Common ratio

    See Geometric sequence.

  • Coordinate(s) of a point

    The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian three-dimensional space

  • Elementary row operations

    The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

  • Frequency

    Reciprocal of the period of a sinusoid.

  • Initial side of an angle

    See Angle.

  • Leaf

    The final digit of a number in a stemplot.

  • Line of symmetry

    A line over which a graph is the mirror image of itself

  • 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

  • Numerical model

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

  • Pascal’s triangle

    A number pattern in which row n (beginning with n = 02) consists of the coefficients of the expanded form of (a+b)n.

  • Perihelion

    The closest point to the Sun in a planet’s orbit.

  • Product of complex numbers

    (a + bi)(c + di) = (ac - bd) + (ad + bc)i

  • Quadratic function

    A function that can be written in the form ƒ(x) = ax 2 + bx + c, where a, b, and c are real numbers, and a ? 0.

  • Radian

    The measure of a central angle whose intercepted arc has a length equal to the circle’s radius.

  • Real part of a complex number

    See Complex number.

  • Sample space

    Set of all possible outcomes of an experiment.

  • Solve graphically

    Use a graphical method, including use of a hand sketch or use of a grapher. When appropriate, the approximate solution should be confirmed algebraically

  • Standard unit vectors

    In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>

  • Zero of a function

    A value in the domain of a function that makes the function value zero.
