Irrationality of E
نویسنده
چکیده
For simplicity, we follow the rules: k, n, p, K, N are natural numbers, x, y, e1 are real numbers, s1, s2, s3 are sequences of real numbers, and s4 is a finite sequence of elements of R. Let us consider x. We introduce x is irrational as an antonym of x is rational. Let us consider x, y. We introduce x as a synonym of x. One can prove the following two propositions: (1) If p is prime, then √ p is irrational. (2) There exist x, y such that x is irrational and y is irrational and x is rational.

We start with irrationality proofs. Historically, the first ones concerned irrational algebraic numbers, like the square roots of non square positive integers. Next, the theory of continued fraction expansion provided a very useful tool. Among the first proofs of irrationality for numbers which are now known to be transcendental are the ones by H. Lambert and L. Euler, in the XVIIIth century, f...
متن کاملA Geometric Proof that Is Irrational and a New Measure of Its Irrationality
1. INTRODUCTION. While there exist geometric proofs of irrationality for √2 [2], [27], no such proof for e, π , or ln 2 seems to be known. In section 2 we use a geometric construction to prove that e is irrational. The proof leads in section 3 to a new measure of irrationality for e, that is, a lower bound on the distance from e to a given rational number, as a function of its denominator. A co...
متن کاملA Generalization to Cantor Series of Sondow’s Geometric Proof that e Is Irrational and His Measure of Its Irrationality
In 2006, Jonathan Sondow gave a nice geometric proof that e is irrational. Moreover, he said that a generalization of his construction may be used to prove the Cantor’s theorem. But, he didn’t do it in his paper, see [1]. So, this work will give a geometric proof to Cantor’s theorem using Sondow’s construction. After, it is given an irrationality measure to some Cantor series, for that, we gene...
