Key Calculus Terms and definitions covered in this textbook
  • Boundary

    The set of points on the “edge” of a region

  • Cubic

    A degree 3 polynomial function

  • Directrix of a parabola, ellipse, or hyperbola

    A line used to determine the conic

  • Distance (in a coordinate plane)

    The distance d(P, Q) between P(x, y) and Q(x, y) d(P, Q) = 2(x 1 - x 2)2 + (y1 - y2)2

  • Focal length of a parabola

    The directed distance from the vertex to the focus.

  • Frequency distribution

    See Frequency table.

  • 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.

  • Graph of a function ƒ

    The set of all points in the coordinate plane corresponding to the pairs (x, ƒ(x)) for x in the domain of ƒ.

  • Horizontal shrink or stretch

    See Shrink, stretch.

  • Inverse tangent function

    The function y = tan-1 x

  • Mean (of a set of data)

    The sum of all the data divided by the total number of items

  • Origin

    The number zero on a number line, or the point where the x- and y-axes cross in the Cartesian coordinate system, or the point where the x-, y-, and z-axes cross in Cartesian three-dimensional space

  • Parametric equations

    Equations of the form x = ƒ(t) and y = g(t) for all t in an interval I. The variable t is the parameter and I is the parameter interval.

  • Partial fraction decomposition

    See Partial fractions.

  • Polar coordinate system

    A coordinate system whose ordered pair is based on the directed distance from a central point (the pole) and the angle measured from a ray from the pole (the polar axis)

  • Rational numbers

    Numbers that can be written as a/b, where a and b are integers, and b ? 0.

  • Reflection

    Two points that are symmetric with respect to a lineor a point.

  • Solve a system

    To find all solutions of a system.

  • Transitive property

    If a = b and b = c , then a = c. Similar properties hold for the inequality symbols <, >, ?, ?.

  • Unit vector in the direction of a vector

    A unit vector that has the same direction as the given vector.
