The correct Answer is:

C

यदि f(x)="log"(1-x)/(1+x), तब f[(2x)/(1+x^(2))]=
Text Solution
|
If f(x)=log((1+x)/(1-x)) show that f((2x)/(1+x^(2)))=2(f(x))
Text Solution
|
If f(x)=log[(1+x)/(1-x)], then prove that f[(2x)/(1+x^2)]=2f(x)dot
Text Solution
|
If f(x)="log"(1+x)/(1-x) , then prove that: f((2x)/(1+x^(2)))=2f(x)
Text Solution
|
If f(x)=log((1+x)/(1-x)), "then f "((2x)/(1+x^(2))) is equal to
Text Solution

यदि f (x) = log ((1+x)/(1-x)), तो साबित करें कि f,((2x)/(1+x^(2))) ...
Text Solution

यदि f(x)= log . (1-x)/(1+x), तो सिद्ध करें कि f((2x)/(1+x^(2)))=2f(x)...
Text Solution

यदि f(x) = "log"(2) ((1-x)/(1+x)), तो f((2x)/(1+x^(2))) बराबर है-
Text Solution
