`sin47^(@)cos17^(@)-cos47^(@)sin17^(@)=(1)/(2)`.

sin47^(@)+cos77^(@)=cos17^(@)

Choose the correct answer in each of the following questions: sin47^(@)cos43^(@)+cos47^(@)sin43^(@)=?

The value of (sin43^(@)cos47^(@)+cos43^(@)sin47^(@)) is

" The value of ((sin17^(@))(cos13^(@))+(cos17^(@))(sin13^(@)))/((cos23^(@))(cos37^(@))-(sin157^(@))(sin37^(@))) is equal to

((sin49^(@))/(cos41^(@))-(cos17^(@))/(sin73^(@)))=?

(sin19^(@))/(cos71^(@))+(cos73^(@))/(sin17^(@))

(cos17^(@)+sin17^(@))/(cos17^(@)-sin17^(@))=?

The value of (sin43^(@) Cos47^(@) + cos43^(@) sin47^(@)) is …….. .

The value of (sin43^(@))/(cos47^(@))+(cos19^(@))/(sin71^(@))-8cos^(2)60^(@) is

(cos(17^(@))+sin(17^(@)))/(cos(17^(@))-sin(17^(@)))= …………
