Hello everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I have an integral of the following form:

log([itex]\int_{r}^{\inf}\frac{P(r,f)}{P(f)}dr)[/itex]

Now, my question is that since the integral is wrt to r, can I bring P(f) outside. So:

[itex]\frac{1}{P(f)}[/itex]log([itex]\int_{r}^{\inf}P(r,f)dr)[/itex]

Thanks,

Luca
