Thank you for responding, I am to quick to think there will be no reply, Its the Latin nature of my Avatar I suppose take all the time you want.
I will add a few more bits-
If we line up the zero points of the two series

Have we got a field where what I referred to as functions can be compared?

Up and down times/divide; side to side plus/minus.
Now what about when we multiply the top series by zero?
Is the result not a series of zeros?

Thank you for your help I will by the next time try to get a bit of the terminology right.
