(cos11^(@)-sin11^(@))/(cos11^(@)+sin11^(@))=

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

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

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

tan theta=(cos11^(0)+sin11^(0))/(cos11^(0)-sin11^(0)) and theta is in the third quadrant,find theta

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

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

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