Hello! :)
Having a hard time managing to solve ad integral in Landau Theoretical Physics Volume 1 page 28 (3rd edition) (Determination of the potential energy from the period of oscillation) The integral is ∫1/√(Eu)(σE) with respect to dE between u and sigma. The book claims that the integral is elementary and should come to equal ∏, yet no matter how many different ways I have attempted this, I have drawn a blank. Any help on the correct derivation would be much appreciated.

Heres an example of this integral on wolframalpha. No explanation is given, and I just can't find a way of doing it.
