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

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

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

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

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

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

Evaluate : 2sin^(2)30^(@)tan60^(@)-3cos^(2)30^(@)sec60^(@)
