" प्रश्न 8."x tan^(-1)x

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

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

Solve for x, tan^(-1)(x+1) +tan^(-1) (x-1) =tan^(-1) ((8)/(31)) .

Solve for x: - tan^(-1)("x"+1)+tan^(-1)("x"-1)=tan^(-1) (8/31)

Solve for x, "tan"^(-1)(x+1)+"tan"^(-1)(x-1)="tan"^(-1)8/(31)[0ltxlt1] .

The sum of possible values of x for tan^(-1) ( x + 1) + cot ^(-1) ((1)/( x - 1)) = tan^(-1)((8)/( 31)) is :
