` sin 22^(@) cos 38^(@) + cos 22^(@) sin 38^(@) =`

The value of (sin 38^(@) - cos 68^(@))/( cos 68^(@) + sin 38^(@) is

sin^(2)22^(@)+sin^(2)38^(@)+sin22^(@) sin38^(@)=

The expression (sin 22^(@)cos 8^(@)+cos 158^(@) cos 98^(@))/(sin 23^(@) cos 7^(@)+cos 157^(@) cos 97^(@)) when simplified reduces to

The expression (sin 22^(@)cos 8^(@)+cos 158^(@) cos 98^(@))/(sin 23^(@) cos 7^(@)+cos 157^(@) cos 97^(@)) when simplified reduces to

sin38^(@)+sin22^(@)=sin82^(@)

cos38^(@)cos52^(@)-sin38^(@)sin52^(@)=0
