Solution for nonlinear set of equations

[Guest]

I have a set of nonlinear polynomial equations with 3 unknowns. Can SOLVER be
used to solve for the unknowns? Any help is appreciated. I have never used
SOLVER before.
Thanks

Hi Peter,

Maybe one of these may help.

Hi Martin-

Thanks for your reply. Not sure if this would help though. Wgat I need is a
solution to system of 3 simultaneous nonlinear equations.

If you are trying to determine the coefficients for a polynomial fit, then
the equations are linear in the unknown coefficients. Those polynomial
coefficients are easily calcualted by LINEST, as illustrated in MartinW's
link. Perhaps you would find

easier to follow?

If you are trying to solve equations that are actually nonlinear in the
unknowns, then you sould say more about what those equations are.
