`tan^(- 1)((1+x)/(1-x))=pi/4+tan^(- 1)x , xlt1`

Solve the following equations tan^(-1)((1+x)/(1-x))=(pi)/(4)+tan^(-1)x

The relation tan^(-1)((1+x)/(1-x))=(pi)/(4)+tan^(-1)x holds true for all

The relation tan^(-1)((1+x)/(1-x))=(pi)/(4)+tan^(-1)x holds true for all

Prove that : tan^-1((1-x)/(1+x))= pi/4 - tan^-1 x

Prove that tan^-1(1+x)/(1-x) = pi/4 + tan^-1x, x < 1

Solve : tan^(-1)((x+1)/(x-1)) + tan^(-1)( (x-1)/(x)) = pi + tan^(-1) (-7)

Solve : tan^(-1)((x+1)/(x-1)) + tan^(-1)( (x-1)/(x)) = pi + tan^(-1) (-7)

[ If xgt0 then which of the following is true 1) tan^(-1)xgt(x)/(1+x^(2)), 2) tan^(-1)x=(x)/(1+x^(2)) 3) tan^(-1)xlt(x)/(1+x^(2)), 4) tan^(-1)x!=(x)/(1+x^(2))]
