## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$i = \sqrt{-1}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + i q^{3} -2 i q^{7} + 2 q^{9} +O(q^{10})$$ $$q + i q^{3} -2 i q^{7} + 2 q^{9} + 5 q^{11} -5 i q^{17} -5 q^{19} + 2 q^{21} -6 i q^{23} + 5 i q^{27} + 4 q^{29} -10 q^{31} + 5 i q^{33} -10 i q^{37} + 5 q^{41} + 4 i q^{43} -8 i q^{47} + 3 q^{49} + 5 q^{51} + 10 i q^{53} -5 i q^{57} + 10 q^{61} -4 i q^{63} -3 i q^{67} + 6 q^{69} -5 i q^{73} -10 i q^{77} + 10 q^{79} + q^{81} -i q^{83} + 4 i q^{87} + 9 q^{89} -10 i q^{93} -10 i q^{97} + 10 q^{99} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 4q^{9} + O(q^{10})$$ $$2q + 4q^{9} + 10q^{11} - 10q^{19} + 4q^{21} + 8q^{29} - 20q^{31} + 10q^{41} + 6q^{49} + 10q^{51} + 20q^{61} + 12q^{69} + 20q^{79} + 2q^{81} + 18q^{89} + 20q^{99} + O(q^{100})$$
