I need to proof Pfaff's law:

It's supposed to be proven 'by comparing the coefficients of on both sides of the equation'.

I don't know much about hypergeometric functions, but according to this article (pdf file), is given by the integral

where the B denotes the beta function.

If you are willing to accept that formula, then the relation follows very easily by making the substitution in the integral. - May 23rd 2011, 04:02 AMKrakowie
Thanks for your help! I'm trying to work it out right now, I hope I will understand it...
