" 5."tan30^(@)cosec60^(@)+tan60^(@)sec30^(@)

Evaluate : (i) sin60^(@)*cos30^(@)-cos60^(@)*sin30^(@) (ii) tan30^(@)*cosec60^(@)+tan60^(@)*sec30^(@) .

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

(tan30^(@)cos ec60^(@)+tan60^(@)sec30^(@))=?

Evaluate each of the following : tan30^(@)sec45^(@)+tan60^(@)sec30^(@)

The value of (tan30^@ cosec 60^@+tan60^@ sec 30^@)/(sin^2 30^@+4cot^2 45^@-sec^2 60^@) is: (tan30^@ cosec 60^@+tan60^@ sec 30^@)/(sin^2 30^@+4cot^2 45^@-sec^2 60^@) का मान है :

Calculate : sec^(2)60^(@)-cot^(2)30^(@)-(2tan30^(@)"cosec"60^(@))/(1+tan^(2)30^(@)) .

Evaluate the following (sin 30^(@) +tan 45^(@) -cosec 60^(@) )/( sec 30^(@)+cos 60^(@) + cot 45^(@))

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