![]() ![]() Notice the pattern in the two preceding sets of formulas. These equations assume that your sheet has two named ranges: x and y.Ĭ: =EXP(INDEX(LINEST(LN(y),LN(x),),1,2))Įquation: y = (c2 * x^2) + (c1 * x ^1) + bĮquation: y = (c3 * x^3) + (c2 * x^2) + (c1 * x^1) + b You can then use these formulas to calculate predicted y values for give values of x. This article describes how to create formulas that generate the trendline coefficients. Put the corresponding values that are to be plotted along the y-axis into column B. I suggest using Scientific with 14 decimal places if you intend to copy the coefficients into an Excel formula. In fact, you can format the trendline 'label' (displayed formula) so that it displays more precision. In Excel®, put values to be plotted along the x-axis in the rows of column A. The point is: 5E+16 and -3E-04 are rounded approximations. When you add a trendline to a chart, Excel provides an option to display the trendline equation in the chart.
