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

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

Prove that: (cos11^(0)+sin11^(0))/(cos11^(0)-sin11^(0))=tan56^(@)

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

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

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

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

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

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