Find the value of tan56^(@)-tan11^(@)-tan56^(@).tan11^(@) .

Find the value of tan 56^(@)-tan 11^(@)-tan 56^(@).tan 11^(@)

If cot 20^@=p then (tan16 0^(@)-tan11 0^(@))/(1+tan16 0^(@)tan11 0^(@))=

Prove that : tan1^(@)tan11^(@)tan21^(@)tan69^(@)tan79^(@)tan89^(@)=1

sqrt(3)(tan11^(@)+tan19^(@))+tan11^(@)tan19^(@)=

(cos 17^(@) + sin 17^(@))/(cos 17^(@) - sin 17^(@))= ................ A) tan 62^(@) B) tan 56^(@) C) tan 54^(@) D) tan73^(@)

If A = tan11^(@)tan29^(@),B=2cot61^(@)cot79^(@) , then:

(cos^(2)56^(@)+cos^(2)34^(@))/(sin^(@)56^(@)+sin^(2)34^(@))+3tan^(2)56^(@)tan^(2)34^(@)=?

The value of ((1+tan11^(@))(1+tan34^(@)))/((1+tan17^(@))(1+tan28^(@))) is
