(12)(tan^(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^(@))

The value of sin^(2)30^(@).cos^(2)45^(@)+2tan^(2)30^(@)-sec^(2)60^(@) is equal to :

Find the value of (4sin^(2)60^(@)-cos^(2)45^(@))/(tan^(2)30^(@)+sin^(2)0^(@))

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