If f(x)=log((1+x)/(1-x))f(2(x)/(1+x^(2)))=2f(x)

If f(x) =log((1+x)/(1-x)) then prove that: f((x_(1)+x_(2))/(1+x_(1)x_(2)))=f(x_(1)) + f(x_(2))

If : f(x) =log ((1+x)/(1-x)), then show that f(a)+f(b)=f ((a+b)/(1+ab)) and 2f(x)=f ((2x)/(1+x^2)).

If f(x)=log((1-x)/(1+x)) ,|x|<1" and f((2x)/(1+x^(2)))=K .f(x) then 50K=

If f(x) is a polynomial even function such that f(x).f(1/x)=f(x)+f(1/x) and f(2)=65 , then f(-3) =
