Euler numbers

In mathematics, the Euler numbers are a sequence En of integers (sequence in the OEIS) defined by the Taylor series expansion , where is the hyperbolic cosine function. The Euler numbers are related to a special value of the Euler polynomials, namely: The Euler numbers appear in the Taylor series expansions of the secant and hyperbolic secant functions. The latter is the function in the definition. They also occur in combinatorics, specifically when counting the number of alternating permutations of a set with an even number of elements.

Euler's number, derivatives, and the bank at the end of the universe

Euler's number, e, is defined as a limit. The function e to the x is (up to multiplying by a constant) the only function that is its own derivative. How are these two related? In this video you'll find an explanation for this phenomenon using banking interest rates, and a very particular b

Math for Liberal Studies - Lecture 1.2.1 Euler's Theorem

This is the first video lecture for Math for Liberal Studies Section 1.2: Finding Euler Circuits. In this lecture, we learn about Euler's Theorem, which tells us how to detect whether a given graph has an Euler circuit or not. I also explain why Euler's Theorem works the way it does.
