tan60^(@)*cosec^(2)45^(@)+sec^(2)60^(@)*tan45^(@)

Find the value of sin^(3)60^(@) cot 30^(@)-2 sec^(2) 45^(@)+3 cos60^(@) tan45^(@)-tan^(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^(@))

What is the value of sin^(3) 60^(@) cot 30^(@) - 2 sec^(2) 45^(@) + 3 cos 60^(@) tan 45^(@) - tan^(2) 60^(@) ?

tan30^(@)*sec45^(@)+tan60^(@)*sec30^(@)

Find the value of   sec ^(2)45 ^(@) cos 45 ^(@)-"cosec"^(2) 30^(@) tan 45 ^(@)

" (iv) (sin30^(@)+tan45^(@)-cosec60)/(sec30^(@)+cos60^(@)+cot45^(@))

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

Evaluate the following : (sin30^(@)+tan45^(@)-cosec60^(@))/(sec30^(@)+cos60^(@)+cot45^(@))

Evaluate (sin30^(@)+tan45^(@)-cosec60^(@))/(sec30^(@)+cos60^(@)+cot45^(@))
