WebTable of Contents. Isaac Newton ’s calculus actually began in 1665 with his discovery of the general binomial series (1 + x) n = 1 + nx + n(n − 1)/ 2! ∙ x2 + n(n − 1) (n − 2)/ 3! ∙ x3 +⋯ for arbitrary rational values of n. With this formula he was able to find infinite series for many algebraic functions (functions y of x that ... WebAssuming "infinite sum" refers to a computation Use as a general topic instead.

List of representations of e - Wikipedia
The mathematical constant e can be represented in a variety of ways as a real number. Since e is an irrational number (see proof that e is irrational), it cannot be represented as the quotient of two integers, but it can be represented as a continued fraction. Using calculus, e may also be represented as an infinite series, … See more Euler proved that the number e is represented as the infinite simple continued fraction (sequence A003417 in the OEIS): Its convergence … See more The number e can be expressed as the sum of the following infinite series: $${\displaystyle e^{x}=\sum _{k=0}^{\infty }{\frac {x^{k}}{k!}}}$$ for any real number x. In the special case where x = 1 or −1, we have: See more • List of formulae involving π See more The number e is also given by several infinite product forms including Pippenger's product See more Trigonometrically, e can be written in terms of the sum of two hyperbolic functions, See more WebIn mathematics, an exponential sum may be a finite Fourier series (i.e. a trigonometric polynomial ), or other finite sum formed using the exponential function, usually expressed by means of the function. Therefore, a typical exponential sum may take the form. summed over a finite sequence of real numbers xn .
