"a Euler graph" or "an Euler graph"? - Mathematics Stack Exchange
Jul 4, 2023 · 12 I'd use "an Euler graph". This is because the pronunciation of "Euler" begins with a vowel sound ("oi"), so "an" is preferred. Besides, Wikipedia and most other articles uses "an" …
rotations - Are Euler angles the same as pitch, roll and yaw ...
From wiki, I know that Euler angles are used to represent the rotation from three axes independently, which seems like pitch, roll and yaw. But from this wiki, it seems that they are …

How to prove Euler's formula: $e^{it}=\\cos t +i\\sin t$?
Aug 28, 2010 · Euler's formula is quite a fundamental result, and we never know where it could have been used. I don't expect one to know the proof of every dependent theorem of a given …
Transform roll, pitch, yaw from one coordinate system to another
Nov 24, 2020 · 1 I'm trying to figure out how to transform a pose given with Euler angles roll (righthanded around X axis), pitch (righthanded around Y axis), and yaw (left handed around Z …
The interconnection between Hyperbolic functions and Euler's …
Jul 16, 2018 · There is one difference that arises in solving Euler's identity for standard trigonometric functions and hyperbolic trigonometric functions. The difference is that the …
Why is it Euler's 'Totient' Function? - Mathematics Stack Exchange
Dec 13, 2018 · The function ϕ(n) ϕ (n) calculates the number of positive integers k ⩽ n , gcd(k, n) = 1 k ⩽ n , gcd (k, n) = 1. It was found by mathematician Leonhard Euler. In 1879, …
Proof of the formula for Euler's totient function
Feb 20, 2015 · I read on a forum somewhere that the totient function can be calculated by finding the product of one less than each of the number's prime factors. For example, to find …
How to interpret the Euler class? - Mathematics Stack Exchange
24 Well, the Euler class exists as an obstruction, as with most of these cohomology classes. It measures "how twisted" the vector bundle is, which is detected by a failure to be able to …
