Prove that sqrt((1+cos30^@)/(1-cos30^@))=sec 60^@+tan 60^@ .

Prove that sqrt((1+cos 390^(@))/(1-cos 30^@)) = tan 60^@ + sec 60^@

sqrt((1+cos30)/(1-cos30))=sec60+tan60

Prove that : sin60^(@)=2sin30^(@)cos30^(@) .

Prove that : sin60^(@)=2sin30^(@)cos30^(@) .

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

Show that : cos30^(@)=sqrt((1+cos60^(@))/(2))

Show that : cos30^(@)=sqrt((1+cos60^(@))/(2))

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

Prove that : (i) ((tan 60^(@)+1)/(tan 60^(@) - 1))^(2) = (1 + cos 30^(@))/(1 - cos 30^(@)) (ii) 3 "cosec"^(2) 60^(@) - 2 cot^(2) 30^(@) + sec^(2) 45^(@) = 0
