If f(x)=xdot|x|, then its derivative is : (a) 2x (b) -2x (c) 2|x| (d) 2x\ sgn\ x

If f(x)= Sin^(2)x , then derivative of f(x) is.

If f(x) = (1)/(cos xsqrt(1-tan x)) then its anti-derivative F(x) satisfying F(0) = 4 is:

If f(x) = (1)/(cos^2xsqrt(1-tan x)) then its anti-derivative F(x) satisfying F(0) = 4 is:

Suppose the function f(x)-f(2x) has the derivative 5 at x =1 and derivative 7 at x = 2. The derivative of the function f(x)-f(4x) at x = 1, has the value equal to

Let f (x) be a polynomial in x, then the second derivative of f(x^(e)) is
