Lipschitz continuous functions that are everywhere differentiable The function defined for all real numbers is Lipschitz continuous with the Lipschitz constant K = 1, because it is everywhere differentiable and the absolute value of the derivative is bounded above by 1. See the first property listed below under "Properties".Likewise, the sine function is Lipschitz continuous because its derivative, the cosine function, is bounded above by 1 in absolute value. Lipschitz co… Webonly have to prove (6) for g. Consider the following ordinary differential equation R2: du( d a h(t,u). dt dg8(t9un) dun Since g is twice continuously differentiable, h satisfies the (local) Lipschitz condition. So the solution of (7) for the initial condition un(O) = u* is unique, and it is the indifference curve of g through (0, u*).
