If `tan^(-1)((2x)/(1-x^(2)))+cot^(-1)((1-x^(2))/(2x))=(pi)/(3),x in(0,1),`then `(x^(4)+(1)/(x^(4)))` is equal to

tan^(-1)((2x)/(x^(2)-1))+cot^(-1)((x^(2)-1)/(2x))=-(4 pi)/(3)

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

If tan^(-1)((x-1)/(x-2))+cot^(-1)((x+2)/(x+1))=(pi)/(4) , find x.

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

Solve tan^(-1)((x-1)/(x-2))+tan^(-1)((x+1)/(x+2))=(pi)/(4)

Solve for x : tan^(-1)(2x)/(1-x^(2))+cot^(-1)(1-x^(2))/(2x))=pi/3, -1 lt x lt 1 .

tan^(-1)((x-2)/(x-3))+tan^(-1)((x+2)/(x+3))=(pi)/(4) , |x| lt 1

If x_(1)=2tan^(-1)((1+x)/(1-x)),x_(2)=sin^(-1)((1-x^(2))/(1+x^(2))) where x in(0,1), then x_(1)+x_(2) is equal to 0 (b) 2 pi(c)pi pi(d) none of these

Solve for x:tan^(-1)((x-2)/(x-1))+tan^(-1)((x+2)/(x+1))=(pi)/(4)

(tan^(-1)(x-1))/(x-2)+(tan^(-1)(x+1))/(x+2)=(pi)/(4). find
