Question

expande tan
$\tan(teta) \sin(teta)$

​

Answer 1

Hey Friend,
HERE IS YOUR ANSWER...!!!
$let \: theta = \alpha \\ = > \tan( \alpha ) \times \sin( \alpha ) \\ = \frac{ \sin( \alpha ) }{ \cos( \alpha ) } \times \sin( \alpha )$
$= \frac{ { \sin( \alpha ) }^{2} }{ \cos( \alpha ) }$
Otherwise
If Question is tan(theta) × cos(theta)
Then by the same way we can get the answer as sin(theta)
I HOPE IT HELPS...!!!
