If `2tan^(-1)x+sin^(-1)((2x)/(1+x^2) )` is independent of x then :

The complete set of values of x for which 2 tan^(-1)x+cos^(-1)((1-x^(2))/(1+x^(2))) is independent of x is :

The complete set of values of x for which 2 tan^(-1)x+cos^(-1)((1-x^(2))/(1+x^(2))) is independent of x is :

If sin^(-1) ((4x)/(x^(2) + 4)) + 2 tan^(-1) (-(x)/(2)) is independent of x, find the value of x

2 tan^(-1) x = sin^(-1) ((2x)/(1+x^(2))) , 1 le x le 1

If |x| le 1 , then 2tan^(-1)x + sin^(-1)((2x)/(1+x^(2))) is equal to

If |x| le 1 , then 2tan^(-1)x + sin^(-1)((2x)/(1+x^(2))) is equal to
