How would I expand the following function as a power series, around $eta=0$?
$$g_0(1,eta)=fracleft(fracPVNkTright)_0-14eta$$
Note that:
$$left(fracPVNkTright)_0=1+frac3etaeta_c-eta+sum_k=1^4kA_kleft(fracetaeta_cright)^k$$
Then we have:
$$g_0(1,eta)=fracfrac3etaeta_c-eta+sum_k=1^4kA_kleft(fracetaeta_cright)^k4eta$$

Starting from your last equation: $$g_0(1,eta)=fracfrac3etaeta_c-eta+sum_k=1^4kA_kleft(fracetaeta_cright)^k4eta$$
you have:
$$g_0(1,eta)=frac34(eta_c-eta)+sum_k=1^4frac k4eta_c^kA_keta^k-1$$
The terms after the +
sign are ok, you just need to deal with the expansion of $(eta_c-eta)^-1$. You can give $eta_c$ as a factor, then you have $$frac33eta_cleft(1-fracetaeta_cright)^-1$$
For $|x|<1$ you have $$frac 11-x=x+x^2+x^3+...=sum_n=1^infty x^n$$
$endgroup$
$begingroup$
I believe it should $frac34eta_c$ right? Then is the total answer: $sum_n=1^infty left(fracetaeta_cright)^n+sum_k=1^4frac k4eta_c^kA_keta^k-1$. I need everything to be in terms of $fracetaeta_c$
