Hi, so basically have been looking at http://en.wikibooks.org/wiki/Special_Relativity:_Dynamics#Momentum" and working my way through the maths for myself. However I have hit this point and can't get past it:
\begin{align}
u = \frac{v - u}{1-\frac{uv}{c^2}}
\end{align}
Which should be able to become:
\begin{align}
u = \frac{c^2}{v(1-\sqrt{1-\frac{v^2}{c^2}})}
\end{align}
I have tried and tried but can't seem to get it to work. Can anyone help me out on this one please?!
Thanks
James
