`sqrt(3)cosec20^(@)-sec20^(@)` का मान किसके बराबर है ?

sqrt(3)cos sec20^(0)-sec20^(@)

Q.sqrt(3)cos ec20^(@)-sec20^(@)=

sqrt3" cosec "20^(@)-sec20^(@)=

sqrt3"cosec"20^(@) - sec20^@ =

sqrt(3)" cosec "20^(@)-sec20^(2)=?

sqrt2 "cosec"20^@ sec20^@ =

The value of (sin^2 60^@+cos^2 30^@- sec 35^@.sin 55^@)/(sec 60^@+cosec 30^@) is equal to: (sin^2 60^@+cos^2 30^@- sec 35^@.sin 55^@)/(sec 60^@+cosec 30^@) का मान किसके बराबर है?

sqrt(2)* " cosec " 20^(@) sec 20^(@)=
