$q$-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.

 $$f(q)$$ $$=$$ $$q - q^{7} + 3 q^{9} +O(q^{10})$$ $$q - q^{7} + 3 q^{9} -2 i q^{11} + 4 i q^{13} -2 q^{17} + 4 i q^{19} -4 q^{23} + 5 q^{25} + 6 i q^{29} + 8 q^{31} + 2 i q^{37} + 2 q^{41} -10 i q^{43} + q^{49} -2 i q^{53} + 8 i q^{59} + 8 i q^{61} -3 q^{63} + 2 i q^{67} + 14 q^{73} + 2 i q^{77} + 4 q^{79} + 9 q^{81} + 12 i q^{83} + 6 q^{89} -4 i q^{91} + 6 q^{97} -6 i q^{99} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 2q^{7} + 6q^{9} + O(q^{10})$$ $$2q - 2q^{7} + 6q^{9} - 4q^{17} - 8q^{23} + 10q^{25} + 16q^{31} + 4q^{41} + 2q^{49} - 6q^{63} + 28q^{73} + 8q^{79} + 18q^{81} + 12q^{89} + 12q^{97} + O(q^{100})$$
