If f(x) = sgn(x^5) , then which of the following is/are false (where sgn denotes signum function)

If f(x) = x^(3) sgn (x), then

If f(x) = x^(3) sgn (x), then

If f(x)=x^3sgn(x), then

Let sgn (x) denote the signum function of x. Let A = {x|x ne 1/2npi, n in Z} Define f : A to R by f(x) = sgn(cos x) + sgn (sinx) + sgn (tan x) + sgn (cot x) Then range of f is

If f(x)=sgn(x^(5)), then which of the following is/are false (where sgn denotes signum function)

The int_(0)^(pi//2)sgn(sin^2x-sinx+1/2) dx is equal to , (where , sgn (x) denotes the sigum function of x)

If f(x)=x^(3)sgn(x), then
