Compute integral (1 to 2) dx/((x)*(x-m)) if m is a small positive number.

What happens as m-->0+

Compute integral (1 to 2) dx/((x^2)+n) if n is a small positive number.

What happens when n-->0+

From the look of it, these integrals will be equal as both both n and m approach 0...the problem is I don't know how to show this.....
