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

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

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)=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

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

Given f'(1)=1 and (d)/(dx)f(2x))=f'(x)AA x>0 If f'(x) is differentiable then there exists a numberd x in(2,4) such that f''(c) equals
