    See Inverse tangent function.

  • Common ratio

    See Geometric sequence.

  • Cone

    See Right circular cone.

  • Course

    See Bearing.

  • Derivative of ƒ at x a

    ƒ'(a) = lim x:a ƒ(x) - ƒ(a) x - a provided the limit exists

  • Distance (on a number line)

    The distance between real numbers a and b, or |a - b|

  • DMS measure

    The measure of an angle in degrees, minutes, and seconds

  • Imaginary axis
