Hi everyone, I need help with a derivation I'm working on, it is the differentiation of the norm of the gradient of function F(x,y,z):(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\frac{∂}{∂F}[/itex](|∇F|[itex]^{α}[/itex])

The part of [itex]\frac{∂}{∂F}[/itex]([itex]\frac{∂F}{∂x}[/itex]) is bit confusing.

(The answer with α=1 is div([itex]\frac{∇F}{|∇F|}[/itex]), where div stands for divergence.)

Any ideas? many thanks!
