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

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

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

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

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

(tan60^@)/(sin60^@+cos30^@)

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 :

The value of 2tan 45^(@)- sec 60^(@)+ cosec 30^(@) is

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