Key Calculus Terms and definitions covered in this textbook
  • Arccosine function

    See Inverse cosine function.

  • Cosecant

    The function y = csc x

  • Factor

    In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

  • Factored form

    The left side of u(v + w) = uv + uw.

  • Factoring (a polynomial)

    Writing a polynomial as a product of two or more polynomial factors.

  • Finite series

    Sum of a finite number of terms.

  • Focal length of a parabola

    The directed distance from the vertex to the focus.

  • 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.

  • Ordered set

    A set is ordered if it is possible to compare any two elements and say that one element is “less than” or “greater than” the other.

  • Power function

    A function of the form ƒ(x) = k . x a, where k and a are nonzero constants. k is the constant of variation and a is the power.

  • Product rule of logarithms

    ogb 1RS2 = logb R + logb S, R > 0, S > 0,

  • Range of a function

    The set of all output values corresponding to elements in the domain.

  • Sequence of partial sums

    The sequence {Sn} , where Sn is the nth partial sum of the series, that is, the sum of the first n terms of the series.

  • Solve an equation or inequality

    To find all solutions of the equation or inequality

  • Sum of an infinite series

    See Convergence of a series

  • Sum of complex numbers

    (a + bi) + (c + di) = (a + c) + (b + d)i

  • Unbounded interval

    An interval that extends to -? or ? (or both).

  • Vertex form for a quadratic function

    ƒ(x) = a(x - h)2 + k

  • Vertical asymptote

    The line x = a is a vertical asymptote of the graph of the function ƒ if limx:a+ ƒ1x2 = q or lim x:a- ƒ1x2 = q.

  • y-axis

    Usually the vertical coordinate line in a Cartesian coordinate system with positive direction up, pp. 12, 629.
