Find `x` If `tan^(-1)(x^(-1))=cot^(-1)((4)/(x))`

Find x if tan^(-1)(sqrt(3))+cot^(-1)x=pi/2

Find the value of tan^(-1)((x-2)/(x-1))+tan^(-1)((x+2)/(x+1))=pi/4

Find the value of tan^(-1)(-x)-cot^(-1)(-1/x),x gt0

If tan^(-1)((x-1)/(x-2))+tan^(-1)((x+1)/(x+2))=pi/4 , then find the value of x .

If tan^(-1)((x-1)/(x-2))+tan^(-1)((x+1)/(x+2))=pi/4, then find the value of xdot

Prove that : tan^(-1) x+cot^(-1) y = tan^(-1) ((xy+1)/(y-x))

If y= tan^-1((1-x)/(1+x))+cot^-1((1-x)/(1+x)) then dy/dx = ?

If tan^(-1).(1)/(2x+1)+tan^(-1).(1)/(4x+1)=cot^(-1)((x^(2))/(2)) , then the number of all possible values of x is/are

intx^(51)(tan^(- 1)x+cot^(- 1)x)dx=

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