$q$-expansion

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

\(f(q)\) \(=\) \( q -i q^{2} - q^{4} + i q^{8} +O(q^{10})\) \( q -i q^{2} - q^{4} + i q^{8} + ( -1 - i ) q^{11} + q^{16} -i q^{17} -2 i q^{19} + ( -1 + i ) q^{22} -i q^{25} -i q^{32} - q^{34} -2 q^{38} + ( 1 + i ) q^{41} + ( 1 + i ) q^{44} + i q^{49} - q^{50} - q^{64} + i q^{68} + ( -1 + i ) q^{73} + 2 i q^{76} + ( 1 - i ) q^{82} + ( 1 - i ) q^{88} + ( 1 - i ) q^{97} + q^{98} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{4} + O(q^{10}) \) \( 2q - 2q^{4} - 2q^{11} + 2q^{16} - 2q^{22} - 2q^{34} - 4q^{38} + 2q^{41} + 2q^{44} - 2q^{50} - 2q^{64} - 2q^{73} + 2q^{82} + 2q^{88} + 2q^{97} + 2q^{98} + O(q^{100}) \)
