Key Calculus Terms and definitions covered in this textbook
  • Compound interest

    Interest that becomes part of the investment

  • Direct variation

    See Power function.

  • Elements of a matrix

    See Matrix element.

  • 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.

  • Hyperbola

    A set of points in a plane, the absolute value of the difference of whose distances from two fixed points (the foci) is a constant.

  • Identity function

    The function ƒ(x) = x.

  • Inequality symbol or

    <,>,<,>.

  • Leading coefficient

    See Polynomial function in x

  • Limit to growth

    See Logistic growth function.

  • Lower bound of f

    Any number b for which b < ƒ(x) for all x in the domain of ƒ

  • Midpoint (in Cartesian space)

    For the line segment with endpoints (x 1, y1, z 1) and (x2, y2, z2), ax 1 + x 22 ,y1 + y22 ,z 1 + z 22 b

  • Order of magnitude (of n)

    log n.

  • Permutation

    An arrangement of elements of a set, in which order is important.

  • Reciprocal function

    The function ƒ(x) = 1x

  • Right angle

    A 90° angle.

  • RRAM

    A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the right-hand end point of each subinterval.

  • Simple harmonic motion

    Motion described by d = a sin wt or d = a cos wt

  • Spiral of Archimedes

    The graph of the polar curve.

  • 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>

  • Vertices of a hyperbola

    The points where a hyperbola intersects the line containing its foci.
