Hello everyone,

is there a smart way to evaluate the Eisenstein series for $\operatorname{SL}_2(\mathbb{Z})$ of weight 4 and 6 at specific points $z\in\mathbb{H}$? If not, how does one obtain the coefficients of the $q$-expansions? The method coefficients(X) is not defined for the Eisenseries module if I understand the documentary.

I'm very happy for any help.
