(sin(63+sin27)/(cos4^(@)+cos25^(@))

Find the value of (sin25^(@))/(cos35^(@))-(cos25^(@))/(sin35^(@))

cos57^(@)+sin27^(@)=

Solve the following: ((sin 27^@)/(cos 63^@))- ((cos 27^@)/(sin 63^@))^2

Evaluate: ( i ) (sin^(2)63+sin^(2)27)/(cos^(2)17+cos^(2)73)( ii) sin25^(@)backslash cos65^(@)+cos backslash25sin backslash65

(sin 65^(@) + sin 25^(@))/( cos 65^(@) + cos 25^(@))=

Evaluate: sin 25^(@) cos 65^(@) + cos 25^(@) sin 65^(@) .

Evaluate sin 27 ^(@) sin 63 ^(@) - cos 63^(@) cos 27 ^(@)

The value of (sin25^(@)cos65^(@)+cos25^(@)sin65^(@))/(tan^(2)27^(@)-cos ec^(2)20^(@))

Show that (cos27^(@)+sin27^(@))/(cos27^(@)-sin27^(@))=cot18^(@)
