Hey there!
Sin²∅ /cos²∅- sin² ∅
=(sin²∅- sin²∅ cos²∅ )/cos² ∅
=sin² ∅(1 -cos ² ∅ )/cos² ∅
=sin²∅ sin²∅ /cos²∅
=sin²∅ tan² ∅
hope helped!
Here,
tan∅ = sin∅ / cos∅
and
sin²∅+ cos²∅=1
1- cos²∅= sin²∅
Sin²∅ /cos²∅- sin² ∅
=(sin²∅- sin²∅ cos²∅ )/cos² ∅
=sin² ∅(1 -cos ² ∅ )/cos² ∅
=sin²∅ sin²∅ /cos²∅
=sin²∅ tan² ∅
hope helped!
