$q$-expansion

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

\(f(q)\) \(=\) \( q - q^{3} + q^{5} -i q^{7} +O(q^{10})\) \( q - q^{3} + q^{5} -i q^{7} -i q^{11} - q^{15} + i q^{21} + q^{25} + q^{27} + ( 1 - i ) q^{31} + i q^{33} -i q^{35} -i q^{37} -i q^{41} + ( -1 + i ) q^{43} + i q^{47} + i q^{53} -i q^{55} + ( -1 + i ) q^{61} - q^{71} + q^{73} - q^{75} - q^{77} + ( 1 + i ) q^{79} - q^{81} + i q^{83} + ( -1 + i ) q^{89} + ( -1 + i ) q^{93} + ( 1 - i ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{3} + 2q^{5} + O(q^{10}) \) \( 2q - 2q^{3} + 2q^{5} - 2q^{15} + 2q^{25} + 2q^{27} + 2q^{31} - 2q^{43} - 2q^{61} - 2q^{71} + 2q^{73} - 2q^{75} - 2q^{77} + 2q^{79} - 2q^{81} - 2q^{89} - 2q^{93} + 2q^{97} + O(q^{100}) \)
