linear regression - Excel Get coefficientsof 3th order polynomial in cell -


i want in cells, coefficients of calculated 3th order polynomial in excel. function used in excel linest. not able use it.

i report example of data.

ydata = [3.669, 2.471, 0.999 0.5] xdata = [44.6, 62.6, 91.0, 100]

the interpolation curve @ 3th order is: 0.7022x^3 -3.4194x^2 -14.142 + 107.84

my goal coefficients of polynomial in cells.
