I feel this blog as a reflection of my thoughts to myself , and sometimes as a public diary, and the is my only friend to share my thoughts who says never a "oh no! ,you shouldn't....That is boring...."

Roots of Polynomials

Abstract: "We discuss four classical theorems on roots of polynomials. They relate to four
different branches of Mathematics, namely, Geometry, Topology, Complex Analysis and
Functional Analysis. The theorems are stated below:
Theorem 1 (Lucas). Every root of the derivative of a polynomial lies within the convex
polygon formed by the roots of that polynomial.
Theorem 2: The roots of a polynomial vary continuously with its coefficients.
Theorem 3 (Cauchy): If all the coefficients of a polynomial lie in the unit disc D, then all
the roots lie in the disc 2D.
Theorem 4 (Bernstein): The norm of the linear operator D (namely the differentiation) on
(The space of polynomials of degree at most n on D) is exactly n."
d1 and d2 are densities of gold and the stone, resp.
densities can be found by the standard density tables online for various stones and gold types.
M and V are the total mass and volume of the ornament.
Mass is easy.
Volume can be easily found by dipping in water in a graduated cylinder or volumetric glass of chemistry lab.
