\begin{gathered}\begin{gathered}1. \: \: \sin(2 \alpha ) = 2 \sin( \alpha ) \cos( \alpha ) \\\end{gathered} 1.sin(2α)=2sin(α)cos(α)\end{gathered}1.sin(2α)=2sin(α)cos(α)1.sin(2α)=2sin(α)cos(α)

2. \: \: \sin(180 - \alpha ) = \sin( \alpha )2.sin(180−α)=sin(α)2.sin(180−α)=sin(α)2.sin(180−α)=sin(α)

3. \: \: \sin(90 - \alpha ) = \cos( \alpha )3.sin(90−α)=cos(α)3.sin(90−α)=cos(α)3.sin(90−α)=cos(α)

=cos(90−10)sin(30)cos(90−40)cos(90−70)=cos(90−10)sin(30)cos(90−40)cos(90−70)

=cos(80) 2/1=cos(80)2/1

cos(40)cos(20)= 4sin(20)1cos(40)cos(20)=4sin(20)1

cos(80)cos(40).2sin(20)cos(20)= 8sin(20)1cos(80)cos(40).2sin(20)cos(20)=8sin(20)1

cos(80)2.cos(40)sin(40)= 16sin(20)1cos(80)2.cos(40)sin(40)=16sin(20)1

2cos(80)sin(80)= 16sin(20)12cos(80)sin(80)=16sin(20)1

sin(160)= 16sin(20)1sin(160)=16sin(20)1

sin(180−20)= 16sin(20)1sin(180−20)=16sin(20)1

sin(20)= 16/1sin(20)=16/1
