1 Introduction 2 Why Polynomials?
... This is precisely the role that polynomials play in connection with other functions: almost every function that we want to study can be built from polynomials in such a way that these polynomials will tell us a little about the value of the function on some interval and the function’s derivatives - ...

... As an application, we prove: Proposition. Every rational number can be written in lowest terms. That is, every q ∈ Q can be written as q = ab where a and b are integers with no common factor greater than one. Proof. Let A be the set of values of |b| for all fractions ab which cannot be written in lo ...
