Answer 2

Answer:

$\tt \mapsto \{ \sin( \alpha ) + \cos( \alpha ) {}^{2} \} \\ \tt \mapsto { \sin( \alpha ) }^{2} + { \cos( \alpha ) }^{2} + 2 \sin( \alpha ) \times \cos( \alpha ) \\ \tt \mapsto { \sin}^{2} \alpha + { \cos}^{2} \alpha + 2 \times \sin( \alpha ) \times \cos( \alpha ) \\ \tt \mapsto 1 + 2 \times \sin( \alpha ) \times \cos( \alpha )$
