An inequality about Holder norm












0














Let function $fin C^{1,alpha}(mathbb{R}^{n})$ , and $f(0)=0$. I want to know whether the following estimate is correct or not: There exists a constant $C$ such that



$$||frac{f(x)}{|x|}||_{C^{alpha}}leq C||nabla f||_{C^{alpha}}$$



Thanks!
