Finding Asymptotes from a set of data in Excel
 

Hi

Can anyone help me find asymptote from a set of data in two column x
and y that show the frequency responce of a say a freq. responce of a
electrochem cell in Excel?
Finding it from a function seem relatively easy but without a model for
the data is there a method of finding two lines that meet to produce
the turning point?


Cheers
