Prove that `tan 56^@ = (cos11^@ + sin11^@)/(cos11^@ - sin11^@) `

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

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

Prove that : (cos11^@+ sin11^@)/(cos11^@- sin11^@)= tan 56^@ .

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

tan 7^@ cos 11^@ sin 27^@ is

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

Match the following : {:(,"List - I",,"List - II"),((1),cot((pi)/(4)+theta).cot((pi)/(4)-theta),(a),0),((2),sin(45^(@)+theta)-cos(45^(@)-theta),(b),tan 56^(@)),((3),(cos11^(@)+sin11^(@))/(cos11^(@)-sin11^(@)),(c ),(sqrt(3))/(2)),((4),sin^(2)75^(@)-sin^(2)15^(@),(d),1):}

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