As I was falling asleep yesterday I realised what I did wrong. In setting up the reduction formula, I didn't take out the gamma function and the beta to the alpha LOL...shit.
How did you possibly use integration by parts with them still in the integral lol.

yeh, i guess. I should have taken them out like a normal person lol. Because they were part of the reduction formula they stayed in the reduction formula and so they never cancelled the alpha factorial and the beta^(alpha+1), which was the answer I ended up with.

i hope that's right. my head hurts and i'd hate to see that i fudged the answer. <_<
Yer that's the exact same way I did it. It wasn't that difficult of a question imo, just looks very daunting but once you take out the constants and apply reduction method it becomes pretty simple.

Would a question like this appear in a MX2 exam?
