Key Calculus Terms and definitions covered in this textbook
  • Addition property of inequality

    If u < v , then u + w < v + w

  • Bounded interval

    An interval that has finite length (does not extend to ? or -?)

  • Census

    An observational study that gathers data from an entire population

  • Center

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

  • Constant of variation

    See Power function.

  • Direction vector for a line

    A vector in the direction of a line in three-dimensional space

  • Graph of a polar equation

    The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

  • Intercepted arc

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

  • Jump discontinuity at x a

    limx:a - ƒ1x2 and limx:a + ƒ1x2 exist but are not equal

  • Nonsingular matrix

    A square matrix with nonzero determinant

  • Ordered pair

    A pair of real numbers (x, y), p. 12.

  • 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.

  • Radius

    The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).

  • Real zeros

    Zeros of a function that are real numbers.

  • Regression model

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

  • Remainder theorem

    If a polynomial f(x) is divided by x - c , the remainder is ƒ(c)

  • Sine

    The function y = sin x.

  • System

    A set of equations or inequalities.

  • Weighted mean

    A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.

  • yz-plane

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