If cot^(-1)((1+x)/(1-x))=1/2cot^(-1)(1/x) then x=

solve the following equations Cot^(-1)((1+x)/(1-x))=1/2Cot^(-1)(1/x),xgt0 and x!=1

Differentiate cot^(-1)((1-x)/(1+x)) with respect to x:

Differentiate cot^(-1)((1-x)/(1+x)) with respect to x .

x cot^(-1)x

If x > y > z >0, then find the value of cot^(-1)((x y+1)/(x-y))+cot^(-1)((y z+1)/(z y-z))+cot^(-1)((z x+1)/(z-x))

(1)/(1-cot x)

Solve cot^(-1) ((3x^(2) + 1)/(x)) = cot^(-1) ((1 - 3x^(2))/(x)) - tan^(-1) 6x

Solve cot^(-1) ((3x^(2) + 1)/(x)) = cot^(-1) ((1 - 3x^(2))/(x)) - tan^(-1) 6x
