Abstract
We give q-analogues of three Ramanujan-type series for \(1/\pi \) from q-analogues of ordinary WZ pairs. The first one is a new q-analogue of the following Ramanujan’s formula for \(1/\pi \):
of which another q-analogue was given by the author and Liu early and reproved by different authors. We also present a WZ proof of a q-analogue of Bauer’s (Ramanujan-type) formula and discuss some related congruences and q-congruences.
