`(tanA+tanB)/(tanA-tanB)=sin(A+B)/(sin(A-B)`

If A+B=90^(@) ,then sqrt((tanA.tanB+tanA.cotB)/(sinA.secB)-(sin^(2)B)/(cos^(2)A)) =?

(TanA+TanB)/(Tan(A+B))+(TanA-TanB)/(Tan(A-B))=

Given that tan(A+B)=(tanA+tanB)/(1-tanAtanB) by writing A+B+C=(A+B)+C prove that tan(A+B+C)=(tanA+tanB+tanC-tanAtanBtanC)/(1-(tanAtanB+tanBtanC+tanCtanA)

"If" (tan (A-B)/tanA)+(sin^(2)C)/(sin^(2)A) =1, "show that", tanA tanB = tan^(2) C.

If A and B are acute angles such that tanA=1/2,tanB=1/3 and tan(A+B)=(tanA+tanB)/(1-tanAtanB) , find A+B

Given A=60^(@) and B=30^(@) , prove that : tan(A-B)=(tanA-tanB)/(1+tanA.tanB)

Given A=60^(@) and B=30^(@) , prove that : tan(A-B)=(tanA-tanB)/(1+tanA.tanB)

If A and B are acute angles such that tanA=(1)/(3) , tanB=(1)/(2) and tan(A+B)=(tanA+tanB)/(1-tanAtanB) , Then find the value of A+B .

If A+B=225^(@) , then (tanA)/(1-tanA).(tanB)/(1-tanB)=?
