Math Help - Indefinite Integral

1. Indefinite Integral

I'm working out a problem and reached an integral of the following form. I'm not entirely sure how to evaluate it. I tried substitution and parts but ended up nowhere so far. Any help would be greatly apperciated.

$\int\sqrt{\frac{r}{hr+u}}\,dr$

Where u and h are constants.

2. Re: Indefinite Integral

A solution most likey looks like:

$\frac{1}{h^{3/2} \sqrt{r}}\sqrt{\frac{r}{h r+u}} \left(\sqrt{h} \sqrt{r} (h r+u)-u \sqrt{h r+u} \text{Log}\left[h \sqrt{r}+\sqrt{h} \sqrt{h r+u}\right]\right)$

3. Re: Indefinite Integral

Thanks, but the problem is I'm not even sure how to start getting to that solution.

4. Re: Indefinite Integral

Is u or h a function of r?

5. Re: Indefinite Integral

Sorry I should have mentioned that u and h are constants.
