If `f(x)=sin^(-1) ((2x)/(1+x^2))` then `f(x)` is differentiable on

If f(x)={x^(3),x^(2) =1 then f(x) is differentiable at

If f(x)=max{sin x,sin^(-1)(cos x)}, then f is differentiable everywhere f is always continuous f is discontinuous at x=(n pi)/(2),n in If is not differentiable everywhere

Is the function f(x)= "sin"^(-1)(2x)/(1+x^2) differentiable at x=pm1 ?

If f(x)="sin"^(-1)((1-"cos"2x)/(2"sin"x)) , then |f'(x)| is equal t o

Let f(x)= sin^(-1)((2x)/(1+x^2))AAx in R . The function f(x) is continuous everywhere but not differentiable at x is/ are

Let f(x)= sin^(-1)((2x)/(1+x^2))AAx in R . The function f(x) is continuous everywhere but not differentiable at x is/ are

Let f(x)=sin^(-1)((2x)/(1+x^(2)))AA x in R. The function f(x) is continuous everywhere but not differentiable at x is/ are

If f(x)={'x^2(sgn[x])+{x},0 Option 1. f(x) is differentiable at x = 1 Option 2. f(x) is continuous but non-differentiable at x = 1 Option 3. f(x) is non-differentiable at x = 2 Option 4. f(x) is discontinuous at x = 2
