Abstract
We consider the Noether Symmetry Approach for a cosmological model derived from a tachyon scalar field with a Dirac-Born-Infeld Lagrangian and a potential . Furthermore, we assume a coupled canonical scalar field with an arbitrary interaction potential . Exact solutions are derived consistent with the accelerated behavior of cosmic fluid.
