$q$-expansion

The \(q\)-expansion and trace form are shown below.

\(f(q)\) \(=\) \( q -i q^{2} - q^{4} + i q^{5} + i q^{8} + q^{9} +O(q^{10})\) \( q -i q^{2} - q^{4} + i q^{5} + i q^{8} + q^{9} + q^{10} + q^{16} + q^{17} -i q^{18} -i q^{20} - q^{29} -i q^{32} -i q^{34} - q^{36} -i q^{37} - q^{40} + i q^{41} + i q^{45} - q^{49} - q^{53} + i q^{58} - q^{61} - q^{64} - q^{68} + i q^{72} -i q^{73} - q^{74} + i q^{80} + q^{81} + q^{82} + i q^{85} + 2 i q^{89} + q^{90} -2 i q^{97} + i q^{98} +O(q^{100})\)
