$q$-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.

\(f(q)\) \(=\) \( q + i q^{3} + ( -2 - i ) q^{5} + i q^{7} - q^{9} +O(q^{10})\) \( q + i q^{3} + ( -2 - i ) q^{5} + i q^{7} - q^{9} -4 q^{11} -2 i q^{13} + ( 1 - 2 i ) q^{15} -6 i q^{17} -6 q^{19} - q^{21} -2 i q^{23} + ( 3 + 4 i ) q^{25} -i q^{27} + 6 q^{29} + 2 q^{31} -4 i q^{33} + ( 1 - 2 i ) q^{35} + 8 i q^{37} + 2 q^{39} + 12 q^{41} + 4 i q^{43} + ( 2 + i ) q^{45} + 8 i q^{47} - q^{49} + 6 q^{51} + 2 i q^{53} + ( 8 + 4 i ) q^{55} -6 i q^{57} + 12 q^{59} -10 q^{61} -i q^{63} + ( -2 + 4 i ) q^{65} + 4 i q^{67} + 2 q^{69} -8 q^{71} -2 i q^{73} + ( -4 + 3 i ) q^{75} -4 i q^{77} -8 q^{79} + q^{81} + ( -6 + 12 i ) q^{85} + 6 i q^{87} + 12 q^{89} + 2 q^{91} + 2 i q^{93} + ( 12 + 6 i ) q^{95} -10 i q^{97} + 4 q^{99} +O(q^{100})\)
