## $q$-expansion

sage: f.q_expansion() # note that sage often uses an isomorphic number field

gp: mfcoefs(f, 20)

Coefficients of the $$q$$-expansion are expressed in terms of $$i = \sqrt{-1}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + i q^{3} + 4 i q^{7} + 2 q^{9}+O(q^{10})$$ q + i * q^3 + 4*i * q^7 + 2 * q^9 $$q + i q^{3} + 4 i q^{7} + 2 q^{9} - 6 q^{11} - i q^{13} - 2 q^{19} - 4 q^{21} + i q^{23} + 5 i q^{27} - 9 q^{29} + 5 q^{31} - 6 i q^{33} - 2 i q^{37} + q^{39} - 9 q^{41} - 4 i q^{43} + 3 i q^{47} - 9 q^{49} - 6 i q^{53} - 2 i q^{57} + 2 q^{61} + 8 i q^{63} + 10 i q^{67} - q^{69} - 3 q^{71} - 7 i q^{73} - 24 i q^{77} + 10 q^{79} + q^{81} - 12 i q^{83} - 9 i q^{87} + 4 q^{91} + 5 i q^{93} - 8 i q^{97} - 12 q^{99} +O(q^{100})$$ q + i * q^3 + 4*i * q^7 + 2 * q^9 - 6 * q^11 - i * q^13 - 2 * q^19 - 4 * q^21 + i * q^23 + 5*i * q^27 - 9 * q^29 + 5 * q^31 - 6*i * q^33 - 2*i * q^37 + q^39 - 9 * q^41 - 4*i * q^43 + 3*i * q^47 - 9 * q^49 - 6*i * q^53 - 2*i * q^57 + 2 * q^61 + 8*i * q^63 + 10*i * q^67 - q^69 - 3 * q^71 - 7*i * q^73 - 24*i * q^77 + 10 * q^79 + q^81 - 12*i * q^83 - 9*i * q^87 + 4 * q^91 + 5*i * q^93 - 8*i * q^97 - 12 * q^99 $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q + 4 q^{9}+O(q^{10})$$ 2 * q + 4 * q^9 $$2 q + 4 q^{9} - 12 q^{11} - 4 q^{19} - 8 q^{21} - 18 q^{29} + 10 q^{31} + 2 q^{39} - 18 q^{41} - 18 q^{49} + 4 q^{61} - 2 q^{69} - 6 q^{71} + 20 q^{79} + 2 q^{81} + 8 q^{91} - 24 q^{99}+O(q^{100})$$ 2 * q + 4 * q^9 - 12 * q^11 - 4 * q^19 - 8 * q^21 - 18 * q^29 + 10 * q^31 + 2 * q^39 - 18 * q^41 - 18 * q^49 + 4 * q^61 - 2 * q^69 - 6 * q^71 + 20 * q^79 + 2 * q^81 + 8 * q^91 - 24 * q^99
