This chapter revisits, for real polynomials and departing from the fundamental theorem of Algebra, some classical theorems of Calculus. As applications of them, we shall prove Newton’s inequalities, which generalizes the classical inequality between the arithmetic and geometric means of n positive real numbers, and Descartes’ rule, which relates the number of positive roots of a real polynomial with the number of changes of sign in the sequence of its nonzero coefficients.
