Colin2B,Glad to hear that, I was concerned that because my reply wasn't exactly what you were asking for, it might have been unhelpful.
I'm so glad to receive your reply.
- First of all, thanks a lot, you have clarified it a bit for me.
Not sure about the conclusion that the 2curves never meet. We might have something in textbook, will have a look and get back if I find it.
Hope someone more knowledgeable comes along
