Solve it ! 2 tan^(−1) (√((1−t)(1+t))) − tan^(−1) (1−t) = tan^(−1) t − tan^(−1) (√(1−t^2 ))

$$\mathrm{Solve}\:\:\mathrm{it}\:! \\ $$$$\:\:\mathrm{2}\:\mathrm{tan}^{−\mathrm{1}} \:\sqrt{\left(\mathrm{1}−{t}\right)\left(\mathrm{1}+{t}\right)}\:−\:\mathrm{tan}^{−\mathrm{1}} \left(\mathrm{1}−{t}\right)\:=\:\mathrm{tan}^{−\mathrm{1}} \:{t}\:−\:\mathrm{tan}^{−\mathrm{1}} \:\sqrt{\mathrm{1}−{t}^{\mathrm{2}} } \\ $$
