We give unified modular proofs to all of Gosper's identities on the qconstant Πq. We also confirm Gosper's observation that for any distinct positive integers n1, • • • , nm with m ≥ 3, Π q n 1 , • • • , Πqnm satisfy a nonzero homogeneous polynomial. Our proofs provide a method to rediscover Gosper's identities. Meanwhile, several results on Πq found by El Bachraoui have been corrected. Furthermore, we illustrate a strategy to construct some of Gosper's identities using hauptmoduls for genus zero congruence subgroups.
