2tan ^ (2) 45 ^ (@) + cos ^ (2) 30 ^ (@) - sin ^ (2) 60 ^ (@)

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

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

The value of (cos^(2)60^(@)+4sec^(2)30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@)) is

(5cos^(6)60^(@)+4sec^(2)30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@))

2tan ^ (2) 45 ^ (@) - + cos ^ (2) 30 ^ (@) - sin ^ (2) 60 ^ (@) is

(kcosec^(2)30^(@).sec^(2)45)/(8cos^(2)45^(@).sin^(2)60^(@))=tan^(2)60^(@)-tan^(2)30^(@) , then k = ?

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