  3. 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?
  4. Hi, is there any chance you could help me with the 2nd part please
