sin47^(@)+sin61^(@)-sin11^(@)-sin25^(@)=

Value of sin 47^(@) + sin 61^(@)- sin 11 ^(@)-sin 25 ^(@) is

tan 7^@ cos 11^@ sin 27^@ is

sin47^(@)-sin25^(@)+sin61^(@)-sin11^(@)=

The value of (sin 1^(@) +sin 3^(@) + sin 5^(@) +sin 7^(@))/(cos 1^(@)*cos 2^(@)sin 4^(@)) is __________

((sin 33^(@))/( sin 11^(@) sin 49^(@) sin 71^(@)))^(2) + (( cos 33^(@))/(cos 11^(@) cos 49^(@) cos 71^(@)))^(2) is equal to ______.
