The three important methods of approximation; interpolation,
least- squares, and Chebyshev, are extended into bivariate approximations.
A method of obtaining polynomial approximations for very
general classes of bivariate samples is developed. Bivariate least -
square approximations are reviewed and a method of developing bibariate
orthogonal sequence is derived. A method...
This paper is divided into two parts. The first part
traces (in details providing proofs and examples) the
history of the solutions of polynomial equations(of the
first, second, third, and fourth degree) by radicals from
Babylonian times (2000 B.C.) through 20th century. Also it
is shown that there is no...
