If `sin^2 (2 cos^-1 (tan x)) = 1` then x may be

(sin2x)/(1+cos2x)=tan x

tan ^ (- 1) ((cos x-sin x) / (cos x + sin x)) = tan ^ (- 1) ((1-tan x) / (1 + tan x))

41. If sin(-)((2a)/(1+a^(2)))+sin((2b)/(1+b^(2)))=2tan^(-1)x, then x may be

If sin^(-1)x in (0, (pi)/(2)) , then the value of tan((cos^(-1)(sin(cos^(-1)x))+sin^(-1)(cos(sin^(-1)x)))/(2)) is :

If sin^(-1)x in (0, (pi)/(2)) , then the value of tan((cos^(-1)(sin(cos^(-1)x))+sin^(-1)(cos(sin^(-1)x)))/(2)) is :

tan (cos ^ (-1) x) = sin ((1) / (2)); then x =

'solve tan ( sin − 1 ( cos ( sin − 1 x ) ) ) tan ( cos − 1 ( sin ( cos − 1 x ) ) ) '

If y = Tan ^(-1) ((cos x- sin x)/(cos x + sin x)) then (d ^(2) y)/(dx ^(2))=
