If you simplify this prinicipal argument is tan^-1(tan2) (2 radians=115 degress(approx))
hence prinicipal argument will be (pi-2) refer to the graph of tan^-1tanx.

saksham
after solving for pricipal argument,you will get tan-1tan2......since question is positive(square),therefore answer will be 2-π
