7.4 Cauchy-Euler Equation - University of Utah
www.math.utah.eduorder Cauchy-Euler equation ax2y00+ bxy0+ cy = 0 accounts for almost all such applications in applied literature. A second argument for studying the Cauchy-Euler equation is theoret-ical: it is a single example of a di erential equation with non-constant coe cients that has a known closed-form solution. This fact is due to a change of variables ...

The Wave Equation - Michigan State University
users.math.msu.eduwhen a= 1, the resulting equation is the wave equation. The physical interpretation strongly suggests it will be mathematically appropriate to specify two initial conditions, u(x;0) and u t(x;0). 5.2. One-dimensional wave equations and d’Alembert’s formula This section is devoted to solving the Cauchy problem for one-dimensional wave ...
FINITE DIFFERENCE METHODS FOR SOLVING DIFFERENTIAL …
www.math.ntu.edu.twsolutions generated by the Euler method form a Cauchy sequence. Backward Euler method In many applications, the system is relaxed to a stable solution in a very short period of time. For instance, consider y′ = y¯−y τ. The corresponding solution y(t) →y¯as t∼O(τ). In the above forward Euler method, practically, we should require 1 ...

www-users.cse.umn.eduare based on Euler’s formula, and are of immense importance for solving differential equa-tions and in Fourier analysis. Further examples will appear shortly. There are several ways to motivate the link between harmonic functions u(x,y), meaning solutions of the two-dimensional Laplace equation ∆u= ∂2u ∂x2 + ∂2u ∂y2 = 0, (2.3)
LAPLACE’S EQUATION IN SPHERICAL COORDINATES
www.dslavsk.sites.luc.eduThis is the form of Laplace’s equation we have to solve if we want to find the electric potential in spherical coordinates. First, let’s apply the method of separable variables to this equation to obtain a general solution of Laplace’s equation, and then we will use our general solution to solve a few different problems.
