Hey! I have some homework due in tomorrow and I can't get my head around this question. I would be grateful if someone could help. 
?_0^a?(?x)/(?x+?(a-x))
it's the integral between a and 0 of (root x divided by (root x plus root(a-x)))
the answer is a/2
and I think it would be useful to use
?_0^a?f(x)dx = ?_0^a?f(a-x)dx
thanks
