`tan7 5^0`

The value of (tan7 0^0-tan2 0^0)/(tan5 0^0)=

Evaluate : (2sin68^0)/(cos22^0)-(2cot15^0)/(5tan75^0)-(3tan45^0tan20^0tan40^0tan50^0tan70^0)/5

Prove that tantheta*tan (60-theta)* tan (60 +theta) = tan 3theta and hence find the value of tan5^0*tan55^0*tan65^0*tan75^0

Evaluate :(3cos55^(0))/(7sin35^(@))-(4(cos70^(0)cos ec20^(0))/(7(tan5^(0)tan25^(0)tan45^(@)tan65^(@)tan85^(@)))

Evaluate : tan7^0tan23^0tan60^0tan67^0tan83^0

Evaluate : ( (3cos55^0) / (7sin35^0))-(4/7)(cos70^0cos e c20^0)/(tan5^0tan25^0tan45^0tan65^0tan85^0

Evaluate :tan7^(0)tan23^(@)tan60^(@)tan67^(0)tan83^(@)

The value of cot7(1^0)/2+tan67(1^(@))/2-cot67(1^(@))/2-tan7(1^0)/2 is

(sin150^(0)-5cos300^(0)+7tan225^(0))/(tan135^(0)+3sin210^(0))=

If tan 35^(@) = 0.7 , then tan (-665^@) =
