  It is commonly believed that our Universe has experienced two different
stages of accelerated expansion. The early stage is known as inflation and the
current acceleration is driven by dark energy. Observing inflation and dark
energy dynamics are among the most important aspects of the current
cosmological research. In this paper we make a first detailed probe of possible
degeneracies between dynamical inflation and dark energy in light of current
cosmological observations. We find the inclusion of inflation and dark energy
parameters together make the parameter spaces broader, but interestingly
deviation from scale-invariant primordial spectrum is sightly more favored by
current cosmological observations when one marginalizes over dynamical dark
energy models.
