Thanks & Regards Firstly I would to thank you. Note that you’re not limited to one trendline. But i got interest in trendline for two reasons- first, i saw that it fit the data very well (R^2=0.9996), so instead of calculating area using trapeziod rule, which is relatively more cumbersome than definite integral of a polynomial, I was tempted to use trendline equation; second- when trendline equation did not give the same y value or even near to actual y value then i was intrigued that why did it happen if it fitting so well. Now when you plotted the fitted value using the trendline equation it is very much matching. You can either use a SCATTER plot Do not use the LINE plot because if you have two columns of data it will graph the individually instead of an input-output graph.
