Abstract In this paper we give simple proof of some well known identities using the constant term method. We also show that Ramanujan's sixth order and Gordon and McIntosh's eighth order mock theta functions can be expressed as constant terms in the Laurent series expansion of rational functions of theta functions.

Keywords Mock theta functions, q-series.
