I am analyzing data from an experiment and have found a polynomial that fits the data nicely (minimum degree of 6) and I would like to find a function in a simpler form that fits the data (I am thinking a polynomial term multiplied by an exponential will be the functional form). In order to do this I was thinking that I could convert my polynomial of 6+ terms to a Taylor series and that Taylor series to a "nicer" function.
Is this possible? Or is there a better approach? Is there a method or online resource to do this?
Thank you in advance.
