Euler's formula - Wikipedia
https://en.wikipedia.org/wiki/Euler's_formulaEuler's formula, named after Leonhard Euler, is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function.Euler's formula states that for any real number x: = + , where e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions ...
Differential Equations - Euler's Method
tutorial.math.lamar.edu › Classes › DEDec 03, 2018 · In order to use Euler’s Method we first need to rewrite the differential equation into the form given in (1) (1). y ′ = 2 − e − 4 t − 2 y y ′ = 2 − e − 4 t − 2 y. From this we can see that f ( t, y) = 2 − e − 4 t − 2 y f ( t, y) = 2 − e − 4 t − 2 y. Also note that t 0 = 0 t 0 = 0 and y 0 = 1 y 0 = 1.
Cauchy–Euler equation - Wikipedia
https://en.wikipedia.org/wiki/Cauchy–Euler_equationIn mathematics, an Euler–Cauchy equation, or Cauchy–Euler equation, or simply Euler's equation is a linear homogeneous ordinary differential equation with variable coefficients. It is sometimes referred to as an equidimensional equation. Because of its particularly simple equidimensional structure the differential equation can be solved explicitly.
