We consider the existence of a Noether symmetry in the
scalar-tensor theory of gravity in flat Friedman-Robertson-Walker
(FRW) cosmology. The forms of coupling function ω(ϕ) and
generic potential V(ϕ) are obtained by requiring the
existence of a Noether symmetry for such theory. We derive exact
cosmological solutions of the field equations from a point-like
Lagrangian.
