Solve for x : tan^(-1)(x+2)+tan^(-1)(x-2)=tan^(-1)(8/(79)) , x >0

Solve for x; tan^(-1)(1/2)+tan^(-1)2=tan^(-1)x

tan^(-1)(n+1)+tan^(-1)(n-1)=tan^(-1)(8/31)

Solve for x : tan^(-1)(2+x)+tan^(-1)(2-x)=tan^(-1)2/3 , where x sqrt(3)

Solve the following equations : tan^(-1) (x+1) +tan^(-1) (x-1) = tan^(-1) (8/31 ) , x gt 0

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
