Formula 1 (0. 1. 4) permits us to associate with each solution U of the differential equation (0. 1. 1b) an analytic function g ( z ) of a complex variable. Conversely, the question arises of determining from a given g ( z ) the corresponding solution of the equation (0. 1. 1...
How to find any solution to a single differential equation with two dependent variables? Richard Jensen Richard Jensen Posted 7 months ago An underdetermined system of differential equations may have infinitely many solutions--like a single equation with two dependent variables. How can one find ...
Coincidentally, I was looking a separable coordinate systems recently. These are coordinate systems in which the Helmholtz equation can be solved by separable function, i.e. a coordinate system in which the separation of variables technique will work. TheLaplaciancan take on very different forms in...
We study independent stochastic processes , defined by a stochastic differential equation with diffusion coefficients depending nonlinearly on a random variables and (the random effects).The distributions of the random effects and depends on unknown parameters which are to be estimated from the continuous...
