Is the following relationship true?:(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\frac{\partial (ln(k))}{\partial P}=\frac{1}{k}\frac{\partial k}{\partial P}[/itex]

I am getting both of these terms from a paper on mineral physics and they seem to use both terms interchangeably. If so, how are these related?
