(5sin^(2)30^(@)+cos^(2)45^(@)-4tan^(2)30^(@))/(2sin30^(@).cos30^(@)+tan45^(@))=?

Find the value of : (5sin^(3)30^(@)+cos^(2)45^(@)-4tan^(2)30^(@))/(2sin 30^(@).cos30^(@)+tan45^(@))+cos 0^(@)

Evaluate each of the following : sin30^(@)cos45^(@)+cos30^(@)sin45^(@)

1Evaluate : (5sin^(2)30^(@)+cos^(2)45^(0)-tan^(2)30^(@))/(2sin30^(0)xxcos30^(@)+tan45^(@))

If tan^(2) 45^(@)-cos^(2) 60^(@)=x sin 45^(@) cos45^(@) tan 60^(@) , then find the value of x.

The value of (sin 30^(@) - cos 60^(@) + tan 45^(@))/(cos 90^(@) + tan 45^(@) + sin 90^(@)) is
