If the solution curve of the differential equation $\left( \left( \tan ^ { - 1 } y \right) - x \right) d y = \left( 1 + y ^ { 2 } \right) d x$ passes through the point $( 1,0 )$ then the abscissa of the point on the curve whose ordinate is $\tan ( 1 )$ is\\
(1) 2\\
(2) $\frac { 2 } { e }$\\
(3) $\frac { 3 } { e }$\\
(4) $2 e$
