If `A+B=90^@`, then : `tanA.tanB=...`

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

If A+B=360^(@), " then " (tanA+tanB)/(1-tanAtanB) =__________.

If A+B=45^@ then (1+tanA)(1+tanB)=

If A+B=45^@ then (1+tanA)(1+tanB)=

If A+B=315^@ then (1-tanA)(1-tanB)=

If A+B+C=180^(@) , then (tanA+tanB+tanC)/(tanAtanBtanC)=?

In DeltaABC if m angle C = 90^@ than tanA + tanB = ......(where a,b,c are sides opposite to angles A, B, C respectively).

If A+B=90^(@) then prove that tanA+tanB=(cosec^(2)A)/(sqrt(cosec^(2)A-1)) .

In triangleABC , if angleC=90^(@) then tanA+tanB =
