cos9^(@)-sin9^(@)=

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

Value of (2sin9^(@)sin 21^(@)sin 39^(@)sin 51^(@)cos21^(@)sin 81^(@))/(sin54^(@)) is equal to:-

Value of (2sin9^(@)sin 21^(@)sin 39^(@)sin 51^(@)cos21^(@)sin 81^(@))/(sin54^(@)) is equal to:-

"sin" 51^(@)+cos 81^(@)=cos 21^(@) .

Evaluate sin63^(@)cos27^(@)+cos63^(@)sin27^(@)=

value of (5sin75^(@)sin77^(@)+2cos13^(@)cos15^(@))/(cos15^(@)sin77^(@))-(7sin81^(@))/(cos9^(@)) is

Find the value of (5sin75^(@)sin77^(@)+2cos13^(@)cos15^(@))/(cos15^(@)sin77^(@))-(7sin81^(@))/(cos9^(@))

Find the value of [(sin^(2)22^(@)+sin^(2)68^(@))/(cos^(2)22^(@)+cos^(2)68^(@))+sin^(2)63^(@)+cos63^(@)sin27^(@)]

Answer the following by a number or a word or a sentence : What is the value of (sin^(2)22^(@)+sin^(2)68^(@))/(cos^(2)22^(@)+cos^(2)68^(@))+sin^(2)63^(@)+cos63^(@)sin27^(@) ?
