2. The inequality is used widely in functional analysis, matrix theory, it is proved again from infinitesimal calculus.

3. Isaac Newton and Gottfried Wilhelm Leibniz independently developed the theory of infinitesimal Calculus in the later 17th century

4. This Artifice is that which we have noted in 10 as the fundamental Artifice of the infinitesimal calculus

5. This is normal, and the arbitrary function all can approach with dividing section multinomials because can know from infinitesimal calculus.

6. Calculus is the branch of mathematics that deals with continuous change. Calculus is also called infinitesimal Calculus or “the Calculus of infinitesimals”

7. Calculus, known in its early history as infinitesimal Calculus, is a mathematical discipline focused on limits, continuity, derivatives, integrals, and infinite series
