If `tan^(-1) 3 +tan^(-1)x=tan^(-1)8` then x =

If tan^(-1)(x-1)+tan^(-1)x+tan^(-1)(x+1)=tan^(-1)3x , then x =

If tan^(-1)x+tan^(-1)(1-x)=tan^(-1)(4/3) then x=

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

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

Let |{:(tan^(-1)x, tan^(-1)2x, tan^(-1)3x), (tan^(-1)3x, tan^(-1)x, tan^(-1)2x), (tan^(-1)2x, tan^(-1)3x, tan^(-1)x):}|=0 , then the number of values of x satisfying the equation is

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

Solve tan^(-1)(x-1) +tan^(-1) x +tan^(-1)(x+1)= tan^(-1)(3x) .

If tan^(-1)(x+1)+ tan^(-1)(x-1)= tan^(-1)(8/31) ,then x is equal to

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