" 12"int(cos30^(@)+sin60^(@))/(1+cos60^(@)+sin30^(@))=(sqrt(3))/(2)

Prove that: (cos30^(@)+sin60^(0))/(1+cos60^(@)+sin30^(@))=(sqrt(3))/(2)

cos 60^(@) sin 30^(@) +cos 30^(@) sin 60^(@)=

Prove that: (cos30^0+sin60^0)/(1+cos60^0+sin30^0)=(sqrt(3))/2

sin60^(@).cos30^(@)+cos30^(@)*sin60^(@)

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

(log)_(sin30^(@)cos60^(@))=1

Prove that : sin60^(@)cos30^(@)+cos60^(@).sin30^(@)=1
