Consider please the function F(u,c,V). Find out its algebraic structure knowing that its limit for u=c is sqrt[(1+V/c)/(1-V/c)].(adsbygoogle = window.adsbygoogle || []).push({});

Hint: Physicists know two solutions of it

F(u,V,c)=[1+V/u]/sqrt(1-V^2/c^2)

F(u,V,c)=[1+Vu/c^2]sqrt(1-V^2/c^)

(Is it a consacrated name for the problem? I used anti-limit for it)

Thanks in advance
