    A value ƒ(c) is an absolute maximum value of ƒ if ƒ(c) ? ƒ(x) for all x in the domain of ƒ.

  • Additive identity for the complex numbers

    0 + 0i is the complex number zero

  • Binomial

    A polynomial with exactly two terms

  • Bounded

    A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

  • Common ratio

    See Geometric sequence.

  • Cone

    See Right circular cone.

  • Coordinate plane

    See Cartesian coordinate system.

  • De Moivre’s theorem

    (r(cos ? + i sin ?))n = r n (cos n? + i sin n?)

  • Dihedral angle

    An angle formed by two intersecting planes,

  • Distributive property

    An annuity in which deposits are made at the same time interest is posted.

  • Probability of an event in a finite sample space of equally likely outcomes

    The number of outcomes in the event divided by the number of outcomes in the sample space.

  • Quadrant

    Any one of the four parts into which a plane is divided by the perpendicular coordinate axes.

  • Rose curve

    A graph of a polar equation or r = a cos nu.

  • Shrink of factor c

    A transformation of a graph obtained by multiplying all the x-coordinates (horizontal shrink) by the constant 1/c or all of the y-coordinates (vertical shrink) by the constant c, 0 < c < 1.
