## Main Question or Discussion Point

Hi,

I have problem with the calculation the error caused by the lagrange inversion. Hence, accroding to Lagrange theorem if f(w)=z it is possible to find w=g(z) where g(z) is given by a series. I wonder, if I consider up to N-th term in the Lagrange series, what will be the error caused by this consideration? should it be given by (N+1) term?

Thanks for your recommendation.
