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^(@) ?

(2sin^(2)53^(@)+1+2sin^(2)37^(@))/(3cos^(2)27^(@)-2+3cos^(2)63^(@))=?

Find the value of (2 sin^2 63^@+1+2sin^2 27^@)/(3cos^2 17^@-2+3cos^2 73^@)

Evaluate : (2sin^2 63^@+1+2sin^2 27^@)/(3 cos ^2 17^@-2+3cos^2 73^@)

It is given that sin54^(@)=(sqrt(5)+1)/(4), the value of (64sin^(4)27^(@)-64sin^(2)27^(@)+6)^(2)-15(sin^(2)27^(@)+sin^(2)63^(@)) is equal to

(sin^(2)3A)/(sin^(2)A)-(cos^(2)3A)/(cos^(2)A)=

(sin^(2)3A)/(sin^2A)-(cos^(2)3A)/(cos^2A)=
