`(cos 11^(@) + sin 11^(@))/(cos 11^(@) - sin 11^(@))` का मान है -

Prove that ( cos 11^(@) + sin 11^(@))/( cos 11 ^(@) - sin 11 ^(@)) = tan 56 ^(@).

If tan theta =(cos 11^(@) + sin 11^(@) )/( cos 11^(@)- sin 11^(@)) and theta is the third quadrant find theta .

Prove that tan 56^(@) =("cos " 11^(@) + "sin " 11^(@))/("cos " 11^(@) - "sin "11^(@))

If tan theta = (cos 11^(@)+sin11^(@))/(cos11^(@)-sin11^(@)) and theta is the third quadrant find theta .

(cos10^(@)+sin11^(@))/(cos10^(10)-sin11^(@))=tan56^(@)

Prove that tan56^(@)=(cos11^(@)+sin11^(@))/(cos11^(@)-sin11^(@))
