There is no such thing as a "DC sine wave." I suspect you mean what
would more
correctly be described as a 10 volt peak- to-peak sine wave with a +10
volt DC offset.

Not that it's that important, but I don't see why a "DC sine wave" is
an impossible concept, considering the definition of DC as a current
which flows in one direction:

Maybe you shouldn't believe everything you read. DC has:
1. Constant amplitude (that's not to say you can't change it.
2. Frequency of 0 Hz. Also, a non 0 frequency does not imply polarity
changes.
