➥ UR ANSWER :

\frac{1 + { \tan( \alpha ) }^{2} }{1 + { \cot( \alpha ) }^{2} } = \frac{1 + { \tan( \alpha ) }^{2} }{1 + \frac{1}{ { \tan( \alpha ) }^{2} } } \\ = \frac{1 + { \tan( \alpha ) }^{2} }{1 + { \tan( \alpha ) }^{2} } \times { \tan( \alpha ) }^{2} \\ = 1 \times { \tan( \alpha ) }^{2} \\ = { \tan( \alpha ) }^{2}
