Hello, I am really confused with a particular aspect of integration. If you could help I would be very grateful, thanks.

You know when we do substitution and get everything in terms of 'u'... in the original question we have got the limits in terms of x and then need to find the corresponding u values, right?

But what I do not get is, what do we do when the corresponding 'u' values could take TWO values each instead of ONE.

For example, in this question that I am doing doing now, since there is a sqrt and hence the upper limit could technically be 6 or 2 and the bottom limit could technically be 5 or 3 . Which do we choose as our limits , in such a situation?

In how many ways can a committee of four men and four women be seated in a row if
a) they can sit in any positions - which is 8!
b) no one is seated next to a person of the same sex? < I dont get this?
