We seem to agree :-).
Rich may or may not have transmodrified my expression.

I wrote
          "
Relativistic mass increase is given by M =3D M_rest /sqrt(C^2-V^2)

"
and subsequently noted that I'd missed a factor of C on the top line (which
is obviously needed to stop our tonnes turning into miligrams)
So my corrected sentence is:
        Relativistic mass increase is given by M =3D M_rest x C /sqrt(C^2-V=
^2
)

And
your:
1/sqrt(1-(v^2/c^2))
=3D 1/sqrt((c^2-v^2)/c^2)
=3D c/sqrt(c^2-v^2)
=3D as above
QED.

fwiw - I'd not have been surprised if I was wrong as that was plucked from
memory from probably 2 decades back. I happned toremember it correctly but
I'd have been sure [tm] to hav done it correctly originally, so the Esaki
drive comments still apply - as much or as little as previously :-).
