Derive gibbs-helmholtz equation
WebIn mathematics, the eigenvalue problem for the Laplace operator is known as the Helmholtz equation. It corresponds to the linear partial differential equation. where ∇2 is the Laplace operator (or "Laplacian"), k2 is the eigenvalue, and f is the (eigen)function. When the equation is applied to waves, k is known as the wave number.
