To see this, we integrate the equation with respect to x, from x ′ − ϵ to x ′ + ϵ, where ϵ is some positive number. We write. ∫x + ϵ x − ϵ∂2G ∂x2 dx = − ∫x + ϵ x − ϵδ(x − x ′)dx, and get. ∂G ∂x x ...

In mathematics, a Dirichlet problem is the problem of finding a function which solves a specified partial differential equation (PDE) in the interior of a given region that takes prescribed values on the boundary of the region. The Dirichlet problem can be solved for many PDEs, although originally it was posed for Laplace's equation. how do i enter check boxes in word
