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

    An equation that relates variable quantities associated with phenomena being studied

  • Combination

    An arrangement of elements of a set, in which order is not important

  • Compounded annually

    See Compounded k times per year.

  • Endpoint of an interval

    A real number that represents one “end” of an interval.

  • Equally likely outcomes

    Outcomes of an experiment that have the same probability of occurring.

  • Exponential form

    An equation written with exponents instead of logarithms.

  • Focal width of a parabola

    The length of the chord through the focus and perpendicular to the axis.

  • 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.

  • Heron’s formula

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

  • Linear system

    A system of linear equations

  • Multiplication property of inequality

    If u < v and c > 0, then uc < vc. If u < and c < 0, then uc > vc

  • Positive linear correlation

    See Linear correlation.

  • 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.

  • Residual

    The difference y1 - (ax 1 + b), where (x1, y1)is a point in a scatter plot and y = ax + b is a line that fits the set of data.

  • Right circular cone

    The surface created when a line is rotated about a second line that intersects but is not perpendicular to the first line.

  • Singular matrix

    A square matrix with zero determinant

  • Sinusoid

    A function that can be written in the form f(x) = a sin (b (x - h)) + k or f(x) = a cos (b(x - h)) + k. The number a is the amplitude, and the number h is the phase shift.

  • Transverse axis

    The line segment whose endpoints are the vertices of a hyperbola.

  • x-intercept

    A point that lies on both the graph and the x-axis,.

  • z-coordinate

    The directed distance from the xy-plane to a point in space, or the third number in an ordered triple.
