complex number
     
         a number of the form x+iy where i is the square
        root of -1, and x and y are real numbers, known as the
        "real" and "imaginary" part.  complex numbers can be plotted
        as points on a two-dimensional plane, known as an argand
        diagram, where x and y are the cartesian coordinates.
     
        an alternative, polar notation, expresses a complex number
        as r e^it where e is the base of natural logarithms, and r
        and t are real numbers, known as the magnitude and phase.  the
        two forms are related:
     
        	r e^it = r cost + i r sint
        	       = x + i y
        where
        	x = r cost
        	y = r sint
     
        all solutions of any polynomial equation can be expressed as
        complex numbers.  this is the so-called fundamental theorem
        of algebra, first proved by cauchy.
     
        complex numbers are useful in many fields of physics, such as
        electromagnetism because they are a useful way of representing
        a magnitude and phase as a single quantity.
