" c) Evaluate."tan60^(@)cosec^(2)45^(@)+sec^(2)60tan45^(@).

Evaluate each of the following : tan60^(@)cosec^(2)45^(@)+sec^(2)60^(@)tan45^(@)

Evaluate: "cosec"^(2)30^(@)+sec^(2)60^(@)+tan^(2)30^(@) .

The value of (cosec^2 30^@ sin^2 45^@ +sec^2 60^@)/(tan60^@ cosec^2 45^@- sec^2 60^@ tan45^@) is: (cosec^2 30^@ sin^2 45^@ +sec^2 60^@)/(tan60^@ cosec^2 45^@- sec^2 60^@ tan45^@) का मान है:

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^(@))

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

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

Evaluate :- tan60^@/(sec60^@+cosec60^@) .

Evaluate : sin ^(2)60^(@)tan 45^(@)- cos^(2)45^(@)sec 60^(@)
