摘要

In a recent artcle [Commun. Theor. Phys. (Beijing, China) 47 (2007) 270], Cao et al. Gave some nontrivial solutions of a Riccati equation by using symbolic and algebra computation. They took these solutions, which are in the form of q-deformed hyperbolic and triangular functions as new solutions. In this comment, we will show that these solutions are just the special cases of some known solutions of the Riccati equation and thus they are not new solutions.
