" (W) "f(x)=x^(3)-(1)/(x^(3))" ,then show ind "f(r)+f((1)/(x))=0" ."

If f(x)= x^(3)- (1)/(x^(3)) then show that f(x)+ f((1)/(x))= 0

If f(x)=x^(3)-(1)/(x^(3)), show that f(x)+f((1)/(x))=0

If f(x)=x^(3)-(1)/(x^(3)) show that f(x)+f((1)/(x))=0

If f: R - {0} to R is defined by f(x) = x^(3)-1/(x^3) , then S.T f(x) + f(1//x) = 0 .

If f(x)=x^3-1/(x^3) , show that f(x)+f(1/x)=0.

If f(x)=(1+x)/(1-x), show that: f(2x)=(3f(x)-1)/(3-f(x)) .

If f(x) is a real valued and differentaible function on R and f(x+y)=(f(x)+f(y))/(1-f(x)f(y)) , then show that f'(x)=f'(0)[1+t^(2)(x)].
