$q$-expansion

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

\(f(q)\) \(=\) \( q -i q^{2} - q^{4} + i q^{8} +O(q^{10})\) \( q -i q^{2} - q^{4} + i q^{8} + q^{16} + ( -1 + i ) q^{17} + ( -1 + i ) q^{19} + ( -1 + i ) q^{23} -i q^{32} + ( 1 + i ) q^{34} + ( 1 + i ) q^{38} + ( 1 + i ) q^{46} + ( -1 + i ) q^{47} -i q^{49} -2 q^{53} + ( 1 + i ) q^{61} - q^{64} + ( 1 - i ) q^{68} + ( 1 - i ) q^{76} + 2 i q^{79} -2 i q^{83} + ( 1 - i ) q^{92} + ( 1 + i ) q^{94} - q^{98} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{4} + O(q^{10}) \) \( 2q - 2q^{4} + 2q^{16} - 2q^{17} - 2q^{19} - 2q^{23} + 2q^{34} + 2q^{38} + 2q^{46} - 2q^{47} - 4q^{53} + 2q^{61} - 2q^{64} + 2q^{68} + 2q^{76} + 2q^{92} + 2q^{94} - 2q^{98} + O(q^{100}) \)
