Evaluate : (5 cos^(2)60^@+4cos^(2)30^@ - tan^(2)45^@)/(sin^(2) 30^@+cos^2 60^@)

The value of (4 tan^2 30+1/4 sin^2 90+ 1/8 cot^2 60+ sin^2 30. cos^2 45)/ (sin60.cos30-cos60.sin30) is/ (4 tan^2 30+1/4 sin^2 90+ 1/8 cot^2 60+ sin^2 30. cos^2 45)/ (sin60.cos30-cos60.sin30) का मान है

cos^(2)30^@-sin^(2)30^@=cos60^@

Prove that : cos^(2)30^(@)-sin^(2)30^(@)=cos60^(@)

Prove that : cos^(2)30^(@)-sin^(2)30^(@)=cos60^(@)
