Find the closed form Green’s function for the problem y′′ + 4y = x2, x ∈ (0, 1), y(0) = y(1) = 0 and use it to obtain a closed form solution to this boundary value problem. Solution. We note that the differential operator is a special case of the example done in section 7.2. Namely, we pick ω = 2. Green's second identity establishes a relationship between second and (the divergence of) first order derivatives of two scalar functions. In differential form In vector diffraction theory, two versions of Green's second identity are introduced. One variant invokes the divergence of a cross product and states … See more In mathematics, Green's identities are a set of three identities in vector calculus relating the bulk with the boundary of a region on which differential operators act.

The first step in creating an identity is locating a good one to use. The word “locate” is key here. While it is possible to fabricate an identity from scratch, it is extremely difficult. Build your documentation on a genuine identity, it is a mistake to assume the identity of another living person.
