WebA triangular wave function is continuous, clearly $C^\infty$ on its linear stretches, but has two "corners" per period where only one-sided derivatives exist (of all orders). The single interesting value of the first derivative can be immediately read off from the graph, and does not require differentiating floor and mod functions. 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.
