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

    If u = v and w = z , then u + w = v + z

  • Algebraic model

    An equation that relates variable quantities associated with phenomena being studied

  • Arcsecant function

    See Inverse secant function.

  • Arrow

    The notation PQ denoting the directed line segment with initial point P and terminal point Q.

  • Constant term

    See Polynomial function

  • Decreasing on an interval

    A function f is decreasing on an interval I if, for any two points in I, a positive change in x results in a negative change in ƒ(x)

  • Degree

    Unit of measurement (represented by the symbol ) for angles or arcs, equal to 1/360 of a complete revolution

  • Distributive property

    a(b + c) = ab + ac and related properties

  • Equivalent systems of equations

    Systems of equations that have the same solution.
