LHS=RHS

Hence proved

 \frac{1 -  \tan ^{2}  Ѳ }{cot Ѳ  ^{2} - 1 }  =  \tan ^{2}  Ѳ  \\ LHS \\ \frac{1 -  \tan ^{2}  Ѳ } { \:  \frac{1}{ \tan ^{2} Ѳ  }  - 1} \: \\\frac{1 -  \tan ^{2}  Ѳ } { \:  \frac{1 -  \tan^{2}   Ѳ }{ \tan ^{2} Ѳ  }  } \\    1 -  \tan ^{2}  Ѳ \times  \frac{ \tan ^{2}  Ѳ  }{1 -  \tan ^{2}  Ѳ}    \\  \tan ^{2} Ѳ   =RHS \\ </p><p>Hence  \: proved
