:- It is true that statistical differentiation and
statistical integration is a missing part in mathematics.
Moreover, it is important to understand that mathematics
is only a tool to quantitatively describe physical
phenomena, it cannot replace physical understanding.
There is an assertion that mathematics is the
language of physics but the converse is also true, physics
can be the language of mathematics as in numerical
differentiation and integration.
In this article, physical B-matrix chains are used to
numerically solve single and double definite integrals as
well as numerical differentiation
