I've been using the TREND function in Excel to do curve fitting to some
data. The problem I'm having is that I can not find the actual
coefficients that make up the 6th. Order Polynomial that fitted the
data. I'm looking for something like.....
Ax^6 + Bx^5 + Cx^4 + Dx^3 +
Ex^2 + Fx + G

Where I can used the A, B, C, D, E, F and G coefficients in other
formulas.

Hi,

Have a look at these pages on the subject of trendlines and formula.
