could someone solve for s/p (or p/s) in terms of v?

[Sikz]

To-(To(s/p))=To/[tex]sqrt{1 - v^2 / 299792458^2}

If my symbols stuff isn't right:
To-(To(s/p))=To/[1 - v^2 / 299792458^2]^0.5

Can anyone solve for s/p or p/s in terms of v?

Not that anyone helped me.... But I did it and found my original equation is wrong... So I'll redo it and then bother you guys some more :)
