[sin30^(@)],[cosec^(2)30^(@)*tan^(2)45^(@)-sec^(2)60^(@)]

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

If x sin 60^(@) cos^(2)30^(@) =(tan^(2)45^(@) sec60^(@))/("cosec"60^(@)) , then find the value of x.

Evaluate each of the following :- (cosec^(2)45^(@)sec^(2)30^(@))(sin^(2)30^(@)+4cot^(2)45^(@)-sec^(2)60^(@))

Find the value of cosec^(2)30^(@)sin^(2)45^(@)-sec^(2)60^(@)

Find the value of following expressions : (i) sec^(2)60^(@)cos^(2)45^(@)-cosec^(2)30^(@) (ii) (tan45^(@)cot^(2)60^(@)+tan^(2)30^(@)cot45^(@))/(sin30^(@)+cos60^(@))

If x sin 45^(@) cos^(2)60^(@)=(tan^(2)60^(@) cosec 30^(@))/(sec 45^(@) cot^(2) 30^(@)) then x
