    Fitting exponentials to data in Excel?

    Hello, I was wondering if anyone could help.

    I have a set of data which makes up an exponential curve and was wondering how I get the equation of the curve.

    Is there a way to do this in Excel or does it need to worked out in some other way?

    Any help appreciated.

    create a graph, select the data set, and then add a trendline. then go to format the trendline, and somewhere in there there should be an option to display the equation on the chart. not the most mathematically sound way but it works...

    Can you please give the y vs x data values or tell how your curve is like - line,circle,parabola,hyperbola,ellipse etc?
