`(tan60^(@)+sec 60^(@)-1)/(tan60^(@)-sec 60^(@)+1)="cosec "30^(@)+2sin 60^(@)`

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

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

sin60^(@)*sec^(2)45^(@)-3tan30^(@).4sin60^(@)=

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

(tan60^(@)+sec60^(@)-1)/(tan60^(@)-sec60^(@)+1) A) sec30^(@)+2cos60^(@) B) csc30^(@)+2sin60^(@) C) cot30^(@)+2tan60^(@) D)none of these

Evaluate (tan60^(@)-tan30^(@))/(1+tan60^(@)tan30^(@)) .

Evaluate (tan60^(@)-tan30^(@))/(1+tan60^(@)tan30^(@)) .

((tan60^(@)+1)/(tan60^(@)-1))^(2)=(1+cos30^(@))/(1-cos30^(@))

Show that : (i) (1-sin60^(@))/(cos60^(@))=(tan60^(@)-1)/(tan60^(@)+1) (ii) (cos30^(@)+sin60^(@))/(1+sin30^(@)+cos60^(@))=cos30^(@)

Calculate : (tan60^(@)-tan30^(@))/(1+tan60^(@) tan30^(@))+cos60^(@) cos30^(@)+sin60^(@) sin 30^(@) .
