" 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 :

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

Let f(x) = 2 tan^(-1)x + "sin"^(-1) (2x)/(1 + x^(2)) then

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

Prove that 2tan^(-1)1/x=sin^(-1)((2x)/(x^(2)+1))

If xgt1,"then"2tan^(-1)x+sin^(-1)((2x)/(1+x^(2))) is……………
