(2sin^(2)63+1+2sin^(2)72)/(3cos^(2)17-2+3cos^(2)73)

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

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

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^@)

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

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

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

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

Prove that (sin^(2)3A)/(sin^(2)A)-(cos^(2)3A)/(cos^(2)A)=8cos2A
