Key Calculus Terms and definitions covered in this textbook
  • Categorical variable

    In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

  • Conjugate axis of a hyperbola

    The line segment of length 2b that is perpendicular to the focal axis and has the center of the hyperbola as its midpoint

  • Derivative of ƒ at x a

    ƒ'(a) = lim x:a ƒ(x) - ƒ(a) x - a provided the limit exists

  • Exponential function

    A function of the form ƒ(x) = a ? bx,where ?0, b > 0 b ?1

  • Fitting a line or curve to data

    Finding a line or curve that comes close to passing through all the points in a scatter plot.

  • Hyperboloid of revolution

    A surface generated by rotating a hyperbola about its transverse axis, p. 607.

  • Instantaneous velocity

    The instantaneous rate of change of a position function with respect to time, p. 737.

  • Integrable over [a, b] Lba

    ƒ1x2 dx exists.

  • Linear regression equation

    Equation of a linear regression line

  • 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.

  • Polar distance formula

    The distance between the points with polar coordinates (r1, ?1 ) and (r2, ?2 ) = 2r 12 + r 22 - 2r1r2 cos 1?1 - ?22

  • Range (in statistics)

    The difference between the greatest and least values in a data set.

  • Reflection through the origin

    x, y and (-x,-y) are reflections of each other through the origin.

  • Relation

    A set of ordered pairs of real numbers.

  • Secant line of ƒ

    A line joining two points of the graph of ƒ.

  • Sum identity

    An identity involving a trigonometric function of u + v

  • Sum of two vectors

    <u1, u2> + <v1, v2> = <u1 + v1, u2 + v2> <u1 + v1, u2 + v2, u3 + v3>

  • Tangent

    The function y = tan x

  • 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.

  • Vertex form for a quadratic function

    ƒ(x) = a(x - h)2 + k
