Solve : `tan^(-1)( 1/2) = cot^(-1) x + tan^(-1)( 1/7)`

Solve tan^(-1) x + cot^(-1) (-|x|) = 2 tan^(-1) 6x

Solve: tan^(- 1) (2+x) + tan^(- 1) (2 -x ) = tan^(-1) 2/3

Solve tan^(-1) x gt cot^(-1) x

Prove that : tan^(-1) x + cot^(-1) (1+x) = tan^(-1) (1+x+x^2)

Solve : tan^(-1)((x+1)/(x-1)) + tan^(-1)( (x-1)/(x)) = pi + tan^(-1) (-7)

Solve for x , tan^(-1) ( x + 1) + tan^(-1) x + tan^(-1) ( x - 1) = tan ^(-1) 3

Solve for x , tan^(-1) ( x + 1) + tan^(-1) x + tan^(-1) ( x - 1) = tan ^(-1) 3x

Solve tan^(-1) x + sin^(-1) x = tan^(-1) 2x
